I have a Sun V120 server, and I connected to it via minicom from a linux machine. The problem is that when I connect, immeadiatly starts to receive the letter m as a command and it returns "Unrecognized command", so it is impossible to configure anything ot to give any command whatsoever. Also, sometimes receives all kind of letters, dots and characters, resulting the same and blocking my keyboard. When I connect from a Windows machine via HyperTerminal all is fine.
Here's the setup: One x86 server (Red Hat 4) with two serial connections to an embedded linux device. One serial connection is to a power control so the device can the restarted, and the other is used for a console to this device. Both serial connections use minicom. People on my team VNC to the x86 server, where they find the two minicom sessions waiting for them as they are left open. I would like to automate connecting to the server and communicating over the serial lines.
Supposing I use ssh to the x86 server, could minicom be used over the serial lines without terminating the minicom processes seen through VNC? If not, is there a way to re-open those windows from within the ssh session, so a user who VNCs to the server won't have to reopen them? Could a single ssh connection control two minicom terminals simultaneously, or would there need to be two ssh connections? It is assumed a user and the automated process will *not* try to access the device at the same time; the automation would trigger during off hours.
I picked up two free Sunfires a couple of days ago (Sunfire V210 and Sunfire V240). Obviously, these are RISC machines, so no video, mouse, or keyboard ports. The only way of connecting to them that I know of is through the ALOM interface. I was hoping to use the minicom program that's on my Linux (Slackware 13.1) box to do this. I connected an RJ-45 straight through cable to the serial management port on the Sunfire V240, connected the other end to a Sun 530-3100-01 RJ45 to DB9 adapter, and then plugged the female end of the adapter into the serial port on the Linux box. I set the minicom port settings to the following:
A - Serial Device: /dev/ttyS0 B - Lockfile Location: /var/lock C - Callin Program: D - Callout Program: E - Bps/Par/Bits: 9600 8N1 F - Hardware Flow Control: Yes G - Software Flow Control: No
...and relaunched minicom hoping that it would connect. It does not. It just sits there with a blinking cursor and an "Offline" status.I also attempted to use cu to connect to the Sunfire using the following:# cu -l /dev/ttyS0 -s 9600.I just get the "Connected" message. No prompt, no anything. It just sits there. Same situation on the Sunfire V210.
I am writing an expect script that will automate flashing an embedded device through minicom using a serial connection and am running into problems sending backspaces.The script catches the configuration prompt on startup and can flash the device, but setting the MAC addresses in the fconfig are being problematic.For example, when I run the script, I can set the variables that are defaults by just pressing enter or enter new directives when prompted.. the problem arrises when I need to enter a new MAC address and there is already one set - I need to overwrite it somehow.
If I manually go through fconfig using minicom (minicom version 2.3 (compiled Dec 3 2008)), I can use backspace on my keyboard to remove the old MAC address and enter a new one - no problem.. but with expect.. I am having issues.I tried sending , ^H,10 177. These do not work. Minicom has BS set for the backspace key though.I tried setting it to DEL - no luck.On the other hand, I can send control-C with send "send 03".
Well, upto now i have been using minicom on linux platform.Can any one tell me whether minicom is meant only for linux or is it platform independent?Actually i'm connecting 2 PC's using RS-232 and then passing and viewing the messages using minicom. Both the PC's use Fedora11. Now suppose i want to do the same thing between 2 pc's where one uses linux and other uses windows. So, if minicom is meant only for linux then how to do this?Can some one also suggest some useful links or tutorials regarding this serial communication between to different OS?
I have a netbook which has no serial port. However I use my netbook to connect to Cisco network devices via serial to USB converter. I installed Minicom on my netbook and I don't know how I can tell Minicom to use my USB port rather than default to /dev/ttyS0.
Can anyone tell me how I can change or point Minicom to use my USB port so my serial to USB will work?
i am using eUploader in windows and there is a auto test facility where we can run scripts .Is there a auto test facility in minicom,where after establishing the connection i can run a script?
I just fully installed slack 13.37 on my laptop. I was trying to use minicom. But after I typed the command line 'minicom -s' or 'minicom', I did not get the minicom window, the curson stop at the console and never return back until I kill the minicom process.
I'm using Postgresql 8.4.2-2. I'm trying to remote into my server securely. I figure I could do so with ssh. Apparently I figured correctly, as per, [URL] and [URL] I setup the ssh tunnel. ssh -L 5432:serverip:5432 Then I setup pgadmin3 to connect as follows:
An error has occurred: Quote: An error has occurred: Error connecting to the server: server closed the connection unexpectedly This probably means the server terminated abnormally before or while processing the request.
I'm not sure what the problem is. I can connect with Code: psql from the cli after connecting to the terminal via ssh. So I know that I'm using the correct password.
i tried to connecting from a windows7 client to a linux server through vnc server.But its very slow , is there any alternative for vnc . i heard that samba can be used as a remote desktop tool if its true please reply with configuration details.
Initially i wrongly entered the serial port device as ttys0 and save it. It wont reply due to wrong device selection. Actual device is ttyS0 and i select this and try to save it as dfl,but an message appear as 'cannot write to /etc/minicom/minirc.dfl'
So i have to configure each and every time i open the minicom. how to configure this correctly?
I have setup CentOS as server and Fedora as Client.Now I want to transfer file from server to client through minicom.How to do that?I tried sending file from CentOs and it does have a ASCII format file transfer option while on the other OS only few like xmodem , ymodem and zmodem type of file transfer was present.
is there a way to move the cursor upward in Minicom when connected to another machine ?
I have an embedded system connected to the PC via null-modem. The embedded machine is to "redraw" the screen on the PC every second. Right now it sends the Form Feed command (0Ch) and sends the screen data down to the end of the page. The flow in detail as seen from the embedded sytem:
1) send FF (0Ch) 2) send text "blah blah one two and so on .." 3) goto step 1
This approach works but the minicom screen on the PC flickers due to the Form Feed command. So I need to find a way to move the cursor up (like a reverse vertical tabulation) to the upper left corner of the screen without using the Form Feed command. In a HOWTO I found something like "vertical coupling" that may be used for such cases, but no more hints than that.
I have a usb serial adapter and was happily using minicom with it under openSUSE 11.2. I've upgraded to openSUSE 11.3 and I can only use minicom with this serial adapter as root. I had previously had problems writing to /var/lock under openSUSE 11.2 which I worked around by changing the minicom config to use /tmp as its lock file location.
Unfortunately my laptop doesn't have a built in serial port so I can't tell if its a general problem or something specific to the /dev/ttyUSB0 device. This is the output I get when I run minicom with my regular user account. I get the same output whether the lock file location is set to /tmp or /var/lock
Code:minicom usb0 Device /dev/ttyUSB0 lock failed: Permission denied. Before I started tinkering my user belonged to the following groups groups=16(dialout),33(video),100(users) I've since added 5(tty),14(uucp),21(console) but still no joy.
I installed Fedora 12 in my PC and after that when I tried to use minicom it was not installed. I tried copying the executable of minicom in /usr/bin from another PC and tried using it. But, I was not able to enter any commands in minicom..
I am trying to access an OpenBSD system that I have just installed via my PcBSD system by the use of a serial cable. I have been trying both minicom and cu but I am obviously doing something wrong... cu -l /dev/cuad0 returns /var/spool/lock/LCK...cuad0 Permission Denied. Can't Open lock file. all ports busy. And when I try to connect through minicom I either get a similar lock error, or minicom will sit at the connection screen with (offline status). I feel like the answer to my problems is a rather simple one, but I do not know where else to look for information.
I am working on a embedded target board which runs on linux. The target board is connected to a linux machine through serial port. To bootup the target board, I run the minicom in the linux machine, boot the kernal of the target board through giving the boot command through the serial console (minicom). Now the question is when the target board boots up, it doesn't starts a shell. The rc scripts are getting executed. There are target specific applications getting started from the rc scripts. I appended & to the last launched application. Still I don't get shell prompt.
I'm new to fedora and also new to Linux too. I'm using lenovo SL410 which is not provisioned for serial port. Now I want to configure cisco router via serial-usb (Z-TEK) converter, for that I have installed minicom and still I'm not able to connect to router. Do I need to install driver for converter that I'm using?
I have a router with linux firmware and attached to it a USB modem with which I can do both data and voice.Any other command send through echo method works ok. I was able to send SMS, edit phonebook and many many other stuff, but not make a call.So what is different from sending the call command within Minicom 2.5 and echo it?
I want to connect to my debian server through putty, but only i got is the message - Network error: connection refused. I try with different setting on the server and in putty, but there is no effect.
Here are my settings: for the serveer i use [URL]
Code:
Port 22 # listen address i changed to accept all addresses ListenAddress 0.0.0.0
[code]....
i have no /etc/ssh/ssh_host_key file and try to comment it but with no success. All other lines at the config file was commented.
I was trying to connect my android phone just to send some AT commands using Minicom or Seyon. But I was not able to connect it. I have connected my phone using a USB cable.Do I need to connect my phone through the serial cable by using a minicom connector to be able to send the commands to the phone.Also when I launch it says Initializing Modem...thenModem at /dev/ttyS0 is available. If I try to Dial it says Warning related to the Baud rate.But After that I am not able to do anything.
Minicom was running fine two days ago capturing data from a gage device via a serial cable. Yesterday, users of the data started complaining that they were not receiving any data.
The minicom status line reads offline. Is this part of the problem or is this normal (I never really noticed it before.) All settings on the gage device match the minicom settings.
I am running kubuntu 9.04. I have minicom, Gtkterm and Putty installed. minicom seems to be really good, but I am missing scroll back functionality on there. Either that or I'm a novice with it and don't know how to do it. Putty is a GREAT app. But what I'm finding is that after the terminal runs for a bit, the screen shows characters from the previous lines and goofs up the output. If I move the window, the gibirish disappears. gtkterm is adding several empty lines to any of the screen output.
I am using a Prolific pl2303 USB<=>Serial adapter. dmesg reports everything seems ok when I plug it in (see below) but when I open the ttyUSB0 port in minicom, it is always offline and nothing works. Also, minicom reports:
[code]....
If I plug the adapter into a different machine (Windows) everything works fine. The serial port is setup correctly (9600-8-N-1) What can I do to get this working?

I am having problems connecting to my VNC server. The host machine is running fedora core 15.
In the past I have been able to connect to the machine, but for some I no longer can't.
I have done the following but still am unsure what problem is 1. Verfied the VNC server is running 2. Verified my user "trb" is in the vnc users list 3. I have checked that my port is open (at least i think). i launched a terminal and did "telnet 127.0.0.1 5902" and successfully connected.
My vncservers config file which is located in /etc/sysconfig/vncservers
Code:
Here is the log file from my latest connection attempt.
I've set up an FTP server with vsFTPd, and I can connect when on the same machine that the server is running. However, when attempting to connect from another machine on the internet, or even on the same LAN, the connection always fails. Port forwarding on the router is enabled.
When attempting to connect over the internet via FileZilla, this is displayed:
