[SOLVED] Alternative USB serial port access

ibwood · 08-16-2010, 05:46 PM

Hi everyone,

I was wondering if there is an alternative method to using udev rules in order to get access to the USB serial ports. Is there a command to check the names and give them to you? I'm looking for something along the lines of "ttyUSB". Thanks!

I want to say modemtool maybe? http://linux.maruhn.com/sec/modemtool.html

Hmm it looks to be like modemtool is for Red Hat. Sorry I guess I didn't specify the version of Linux I am using. It's Ubuntu 9.10 Karmic Koala. I'm currently using udev rules to send and receive data from serial ports. I run into a problem when my program tries to read the data. It just draws a blank. I think it's because of the udev rules. Anyone else have this problem?

The command to use for this is:

Code:

$ dmesg | grep tty

with all of the serial ports plugged in. This will list the devices connected to each port by format ttyUSB*
