Substituting LynxTerm for direct commands from Beagleboard

We are using a robotic arm with the SSC-32 board which runs great using LynxTerm on windows. But, for our project we are needing to send commands from a Beagleboard running Angstrom linux. When we run a screen command at baud rate of 115200, it doesn’t do anything at all, or allow commands to be sent. We have installed the ftdi, usbserial, and cdc-acm drivers onto our Beagleboard already.

1.) Is there anything additional to a “screen /dev/ttyUSB0 115200” that needs to be done to setup communication between the Beagleboard and SSC-32?
2.) Can the beagleboard send the hex commands that LynxTerm used to provide the same functionality?

Any help is greatly appreciated!!

The instruction set for the SSC-32 is ascii not hex. I don’t know anything about setting up serial data on a beagle board. Also remember the SSC-32 will not do anything until you send a CR.
