Hardware :: Opensuse 11 Machine Cloned With Dd, With Serial Port Blocking?

Feb 23, 2010

I have cloned an embedded system that runs Opensuse 11 x86 using dd. The embedded system uses a simple serial device, by writing to the relevant device file (/dev/ttyS2, usually). Curiously, when I write to the same serial device on the newly cloned system (which, incidentally, has almost identical hardware), thusly:

echo hello > /dev/ttyS2 the command blocks for up to a minute, before finally returning without making the hardware do anything. I can boot into Opensuse's rescue system on the clone and successfully do exactly the same thing, as I can when I boot the original's "identical" operating system. Why might this problem occur? What can I do about it?

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.

General :: Create A Virtual Serial / COM Port?

Mar 25, 2010

I'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 :: Bash Serial Port Script Wont Hang Up

Oct 12, 2010

My 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.

General :: Wget Seems To Add Extra Newlines On Output To Serial Port ?

Oct 4, 2010

I need to read some data from a web server and output to a serial port on the local machine. I was attempting to use the following command:

Code:

But the device attached to the serial port (a plate embosser) acts as though there is an extra newline after each line of data.

It parses the data sent according to it's own format, which includes a format string in <> followed by a data block containing one data field per line, with the whole block surrounded by <>,

For example:

Code:

seems to output as though it were:

Code:

I can verify that the web server is outputting the former (and it looks correct if I send the wget output to console).
