I'm trying to get the serial interface of my Fedora Core 1 machine to talk to a NuDAM 6053. I have it hooked up in serial with a Nudam 6520 the connected to COM1.

I can not get a response out of the NuDAM 6053 unless I use the Visual Basic admin program on windows.

Any suggestions on how to configure my Fedora box to talk to the module would be appriciated.

Have you tried something like minicom or C-kermit as a terminal? Use something like these to find the right settings then transfer those into your code. I can probably help with any specifics, but my memory is fading. Also make sure you own or can access the port.

Do you get anything when you do:

cat /dev/ttyS0

use Ctrl-C to exit.

Try hooking known working serial devices such as a mouse and see if you get anything.

This might be permission problem on /dev/ttySx

1) You will need a NuDAM-6520 RS-232/RS-485 Converter for your Port.

2) For the communication protocol look in:
