i was using a serial console program (not minicom) two weeks back but took a break and have no idea what it is! man, it was awesome, too. it had a nice gui, similar to hyperterminal...and from what i think i remember it came packaged with f14.
View 4 RepliesI am trying to connect to a cisco console port using the usb to serial converter. I am using minicom and I changed me setting to reflect the USB converter cable, but it isn't working. I have set my baud rate to 9600, 8 data bits and no parity. Minicom acts as if it is connected (it doesn't give any errors), but there is nothing on the screen and nothing happens when I type. Also, I use the tail command and it sees the usb connector connected when I unplug it and plug it back in.

View 1 Replies View RelatedI've got a home server running ubuntu 10.0.4. It have no monitor or keyboard. So I want to access it from a serial console. (I use SSH currently but if something goes wrong, I need to be able to do something... so serial console seems a fine thing). OK, so on the server, I tell grub to output everything on ttyS0 and opened a getty on ttyS0. On the client side (Laptop running Ubuntu 10.0.4 with pl2303 USB to Serial adapter) I use Minicom.
Home server restart:I see grub menu, linux kernel messages, login prompt. But, I can't do anything:In grub or at the login prompt, no key press is recognized by the server.I've got write permission to /dev/ttyUSB0. I tried a different getty (mgetty)with no success.I stopped the getty on ttyS0 on the server. And run minicom.
From the server's minicom, if I type something, it appear on the client screen. From the client's minicom, if I type something, some garbage appear on the server screen :(One of this things for each char typed). If I short-circuit pin 2 and 3 of the client serial port, it echoed what I type. The two serial ports are connected with a nullmodem cable. (seems to be a full handshaking cable). Of course, same serial port config for both minicom, grub and getty. Hope I'm understandable enough. (English not my primary language). Can somebody help me make this *$*#! serial console working right ? I'm on it for 10 hours now with no success...
Edit : I nearly forgot to tell you I had to update the standard ubuntu kernel to 2.6.34-020634rc1-generic because there was a bug in the pl2303 driver in the stock kernel (2.6.32-25-generic) which prevented me from doing anything (even receiving).

I have a dell poweredge server. In the bios, it has the option to redirect the screen to the serial port. There is also the check box "redirection after boot" which from what I understand will let me to continue to use the serial port attached to a terminal as if it was the main VGA monitor with a keyboard attached.
When I start the machine up, everything goes as expected, I see the output from the bios on my serial terminal, until debian actually starts booting. It all goes blank. If i attach a monitor i can see it is indeed booted and waiting at the debian login prompt. What should I do from here? I was under the impression that if i enabled "console redirection after boot" that the os would be none the wiser and i could continue using the serial console as the main screen as needed, but that does not seem to be the case.
I configured the serial consol on centos5 as follows
# dmesg |grep tty
Kernel command line: ro root=/dev/VolGroup00/LogVol00 console=tty0 console=ttyS0,9600n8
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A[code]......
But I could not consol Centos server from my labtop (win xp) Is there missing or wrong configurations ?
I am looking for a solution to administer my remote server running SUSE LINUX 10.1 (X86-64) - Kernel 2.6.16.13-4-smp. I have made changes to server and is able to see the boot process and also able to login to system through serial console.
My question, will I be able to administer the server through serial console incase if my root partition is corrupted and system has gone to maintenance shell(or root shell).
Also is there way to go directly to maintenance shell from grub(not talking about single user mode). I want to go maintenance shell where / partition is not mounted.

I am trying to connect to serial console, local one, just to verify than it works, is is possible?Well, I configure serial console
Code:

# This service maintains a getty on ttyS0 from the point the system is
# started until it is shut down again.

It is started, now I am trying to connect to the console via minicom, is it possible from machine where the console is running?If not, how could I check it remotely?

I've made a LED gadget, which can light up LED patterns. It connects to serial port with RS232 protocol and receives messages which contain desired patterns. My friend wrote a python program which generates patterns and writes them to terminal. Everything is fine this far. I've made a bash script to run this program:
#!/bin/bash
python gen.py
and set it to autostart with:
chmod 755 scr.sh
mv scr.sh /etc/init.d/scr.sh
sudo update-rc.d scr.sh defaults
What I don't understand is - how do I redirect it's output to ttyS0 so that my device could catch generated data?
I've heard that in Linux every data stream can be redirected anywhere with '>>' in bash script. How do I do that? Can I, dunno, write something like this: python gen.py >> ttyS0 in shell script?
Is there a console based applications (/ script) for viewing PDF documents? pdftk can convert, but a cool program, maybe it exists.

View 11 Replies View RelatedI bought a set of 3 laser sensors and it came with a software and its C++ source code for windows to receive the lasers info through the serial port. Since the entire project is running on Linux, I need to port the windows code to Linux. At the present moment, I already can receive the data from each of the 3 sensors, but the info is coming concatenated! Tracking down the original windows code, I found that it is probably happening cause I didn't ported these lines to my Linux version:
Code:
COMMTIMEOUTS CommTimeouts;

CommTimeouts.ReadIntervalTimeout = 2;

I have connected a device to my linux system with a serial cable (rs232). The settings are: port /dev/ttyS0, baud rate=38400, data bits=8, stop bits=1, no parity, no hardware or software handshaking. I wrote a linux program that sends 1 byte to the device, but the device doesn't receive it. I know the serial ports are working because when I use the CuteCOM application to send data, the device DOES receive it, so obviously it is a problem with my code..
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>

I want to simulate a serial protocol in user space program to test reception algorithm. The protocol is similar to UART protocol but frame format is different. The duration of 1 bit is 114,46 us. In my main function I'm creating two threads. Tx for simulating transmitting data and Rx for reception data. For measure time I use create_timer() function and signals. Each thread has its own timer and signal handler. Tx timer uses SIGUSR1 and Rx timer uses SIGUSR2. Tx thread sets the global variable and Rx reads it.
The timers are set to sample with 114,46 us period. When they reach this value signal handler should set the flag. Flag is check in thread and some operation are made. When I set the timers period for longer time (100 ms) everything works fine but when I change it to default value (114,46 us) the Rx thread doesn't receive the proper data. I am wondering if the 114,46 timer period is possible to simulate in user space? Whether the time will give me the proper resolution ? Theoretically it should provide 1 ns resolution.
I would like to know if there is anyway of starting a program via console.

View 3 Replies View RelatedI am having troubles getting used to the new Ubuntu UI - Unity. One thing that bugs me is that I don't know how to find a program if I don't know the program's name. For example I remember I have an IRC client but I don't remember its name and its name does not contain IRC. Before I had Unity, programs were organised in categories, so to find the irc I just looked in the Internet category. The same happened to me with the writer program and others..Can anyone tell me how I can find a program by its category? I was surprised that I could not many complaints like mine on the web. I don't want to give up and go back to the old gnome cause I figure that there is just a learning curve to pass and beside there are some feature in it that I like.
