RHEL - Windows Serial communication + serial to USB adapters
 

So... I have a RHEL 5.8 running on a Dell's PowerEdge R720, and i need to use two USB to serial adapters on both machines, I need to send and receive text messages between this machines.

On Windows 7, I'm using the Hercules serial terminal, configured to 9600 baud, 8 data size, no parity, and no handshake.

When i plug in the USB to serial adapter on the RHEL machine, ttyUSB0 shows up, this makes me think that the Kernel recognize the adapter, and the same for windows, a COM# port becomes available.

On RHEL, i'm using cat /dev/ttyUSB0 9600 cs8 -cstopb -parenb and echo "This is my message" >/dev/ttyUSB0 commands trying to send and receive messages but nothing show up.. so.. Thanks in advance

It would be easier if you used an terminal application like minicom instead of cat.

Make sure you use a NULL MODEM serial cable when connecting two PCs.

Agree with michaelk totally...a null-modem is probably the culprit here. That's something that would snakebite people a LOT years ago. :)
