General :: Create A Virtual Serial / COM Port?
Mar 25, 2010I'm currently working on a project for university that requires communication, via an RS232 link between a piece of hardware (I have designed and am currently testing) and some software(which need testing).
I was hoping to have my hardware finished by now so I could get on with testing the software over Easter.
The hardware does not work yet but I would still like to test the software.
Does any one know if there a way to make a virtual serial port that I could put data on and read data off while my program accesses it as a regular serial port so I can check my code?
I am using Ubuntu 9.10 and am happy to give any more information on request.

General :: Windows With Putty Via USB Serial Cable To Serial Port - Output Ok, Input Isn't?
Jan 13, 2010I 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.

/dev/ttyS3, UART: unknown, Port: 0x02e8, IRQ: 3
but I'm not seeing anything from a GPS receiver in NMEA at 4800 no par 1 stp I know that was working about a year ago. I think udev was not helping ,as I was getting permission denied to the com port, I added myself to group dialout. and no message on startup now
I need to be able to talk to a piece of kit with 9600 baud and nothing. I have win32 s/w to drive it , but it falls over in wine. My laptop still has win7 on it in a tiny partition but no 9w d connector and I'm waiting for a USB converter cable. Too many variables ! I'd forgotten all the hassle of having to install drivers just to get basic things running. But as the stupid thing couldn't manage using the driver for my NIC, I was stuck with hyper-terminal, and nothing from the GPS board @4800 or another piece of equipment running at 9600. I suspect the com port on the new mobo doesn't wan to play

Oct 12, 2010My linux computer runs ubuntu 10.04.
I have it hooked up to a device, and the device manual says:
Device Specs:
Here is my script:
PROBLEM 1: The file gets created and most of the data gets saved to it, but the terminal never goes back to the ~ (home directory?) when finished. I can type whatever I want but it wont go anywhere or do anything even when I press enter. I have to click the X to close it and then the prompt comes up saying something like "are you sure you want to close terminal and kill all processes".
Reset does not work nor does the "stty sane" command that I read would force it to reset.
PROBLEM 2: See the 00/01 character in front of 200 and 201, those are <SOH> commands and in the file they are supposed to show up, sometimes they do, sometimes they don't. But there is always supposed to be an <ETX> after each one, and with the way its written now, no <ETX> shows up, <ETX> is 00/03 i think.
Here is what the output is supposed to look like:
yet the first SOH doesn't show up half the time and none of the ETX show up.
