is it a db9 serial port or a usb port? You can use lsusb in the terminal to get a usb connected devices listing, or use statserial to probe serial ports. If you want to view data information on a serial port you can install gtkterm and run that from terminal to view more information. I've had communication issues with my embedded programmers that utilize an FTDI chip to convert USB to RS232. Still trying to figure it out myself. Hope this helps.

I did some looking around and could not find anything helpful. From what I understand gtkterm hasn't been updated since 2004. The program is fairly straight forward anyway. You can view information on the serial port (data transmitted and received). I'm going to look for an alternative since I am having the same problem. I'll post back when I make some progress.
