CentOS 5 Hardware :: NetMOS PCI 9835 Dual Serial Card - Can't Use The Serial Ports

Feb 21, 2009

On my CentOS 5.2 install I've installed a dual-port serial card based on the NetMOS 9835 chipset. I've followed the serial instructions, but everything they tell me to do is already done - see setserial outputs below. I've compared these values to the lspci output (below, NetMos card is at the bottom of the output) for the card and it appears right. Problem being, I can't use the serial ports. Oh and I did use search, and looked at every 9835-related article before posting this :)

CentOS 5 Hardware :: One Port Of Serial Card Can't Work

May 18, 2010

I add one serical card which is extended to 4 serial ports to my host, but in centos 5.4, only 3 (In my machine, is ttyS1, ttyS2 and ttyS3,ttyS0 is another serial port) of my host can be used, and /dev/ttyS4 doesn't work.

$ sudo cat /dev/ttyS4
cat: /dev/ttyS4: No such device or address

The card info is as follows:

Host> lspci -vvv

Debian Hardware :: Setup A PCI To Serial Port Card?

Jan 13, 2010

I recently purchased a new PCI to Serial card to get 2 serial ports so I can connect my external serial modem and operate hylafax. The machine that I placed this card is a Debian 2.6.26-19lenny2 which is operating just fine. Further more the motherboard is ASUS P5QL-CM. I have managed to place the pci card on an available slot and powered on. I then tried to follow the instructions that the supplier of the card had regarding installation of drivers and this is what I get:

First they asked to untar the contents and make clean. the result is :

debiansrv:/temp/golden# make clean
cd driver;
make clean
make[1]: Entering directory `/temp/golden/driver'
rm -f *~
rm -f *.o

Ubuntu :: Serial MIDI - Doesn't See Any Serial Ports?

Jun 21, 2011

I have a bit of a dilemma. I'm attempting to use a microcontroller to send MIDI messages over a virtual serial port. I want to (eventually) read them with Mixxx. I'm using an FTDI chip, so I get a /dev/ttyUSB0. I've tried spikenzielabs' Serial-Midi program, but it doesn't see any serial ports. NOTEMIDI looks really old and won't compile on my 10.04 LTS machine.

Programming :: PHP Serial Port No Longer Work

Aug 24, 2010

I had a web server running from a Windows 7 computer and recently moved everything to an Ubuntu server. All is set up and running smoothly. I do have one page that actually interfaces with the serial port. The only thing I do with it is to set the DTR pin to "true" which applies +12v to the pin. This activates a relay. It is very basic and simple. After moving everything to Linux, this page will no longer work. I knew this would happen. I know the page had code in it to call out "Com1" which would change to "ttyS0". It also had "set_serDTR(True);" in the code. I can't figure out how to get PHP to control the DTR pin on a Linux serial port.

General :: Windows With Putty Via USB Serial Cable To Serial Port - Output Ok, Input Isn't?

Jan 13, 2010

I am trying to get two way serial communications going between a Windows XP system and a Linux system (RHEL 5).I have /sbin/agetty -L 9600 ttyS0

in /etc/inittab. I am using a generic USB to serial adaptor on Windows (Unitek) and a null modem cable. I have putty configured for 9600 baud, 8 bits, no parity, one stop bit, no flow control.I get the login prompt from agetty in the putty window but input does not work; I see weird characters in the putty screen. I can echo output into the device from windows and see it, but

cat < /dev/ttyS0. just prints out weird characters from what I type.

Hardware :: Serial Ports Through USB Hub

Oct 30, 2010

I need to talk to several serial ports. I was thinking of having a bunch of USB to serial cables and then plugging all of them into a USB hub, which goes to the computer. What I want to know is, will I see each serial port as a separate thing? With 1 USB to serial cable and no hub, I see /dev/ttyUSB0. With this hub, will I see /dev/ttyUSB0, /dev/ttyUSB1, etc?

Debian Hardware :: How To Get Old Serial-touchscreen To Work With USB / Serial Adapter

Oct 9, 2015

I am hoping to be able to get an old serial-touchscreen to work with a usb/serial adapter. I had this touchscreen working some years ago on different hardware. I would like to hook it to the machine I am setting up as a multimedia host with mythtv among other things.

Following the instructions I left behind when I got this to work way back when does not work. See [URL] ....

This info is a work around to get the xserver to see the touchscreen. [URL] ....

I do know that the touchscreen works as I am able to get garbage on the screen as in the first part of my howto. But I have not had any success getting xorg to see it. I wish I had posted a copy of the xorg.conf at the time, but......

There is an issue with the current xserver in testing that I am hoping the next update (in unstable) will fix when it gets pushed to testing. That is that Code: Select all# X -configure fails with a segfault. So I am not able to generate the xorg.conf needed to get it to work. I was going to post a bugreport, that is when I found out there is an update in unstable, so I am waiting for it to get pushed at the moment.

Anyway I am hoping that I can link /dev/ttyUSB0 to /dev/tty0 and get it to work. I would like some kind of guess as to my chances of success before I go to all the work of getting the monitor hooked to the host.

OpenSUSE Hardware :: Permissions For Accessing Serial Ports?

Feb 3, 2010

I am unable to access a serial port as normal user in OS 11.2. The ownership for the port,/dev/ttyS0 belongs to root:dialout. Group dialout has RW permissions.So,I guess the user has to belong to 'dialout' group.Even after a user is included in dialout port,still the user is unable to access,"Permission is Denied".

Before OS 11.2,I used to make the users members of group "uucp" to get serial port access.I tried that also in OS 11.2,without luck.So,I have to be root to access it. This requirement itself seems to be one of the fossils of old time Linux where for normal usage of PC resources,one needed elevated privileges.I guess the trend now is to let the user do all PC work,but in a safe way.

Ubuntu Networking :: Dell WLAN Card - Ethernet Port Does Work

Jul 28, 2010

I have a Dell WLAN 1397 Half Minicard, 802.11 b/g card in my laptop, and I can't seem to get ubuntu to work with it. I tried this method:

1. Synaptic Pack Manager
2. Check "Install from Boot Disc"
3. Reload
4. Install and apply bcmwl-kernel-source
5. Reboot

This didn't work for me, so I tried entering sudo apt-get install bcmwl-kernel-source and that also didn't work. Another thing I tried is formatting my Ubuntu partition and reinstalling, and retrying both of those methods. The ethernet port does work, however.

ser2 = serial.Serial('/dev/ttyUSB1',timeout=2,baudrate=115200)
