[no subject]

When I plug the device in, it says it's being added to "ttyUSB0".  I 
have a /dev/ttyUSB0 with the right character node (188 0) and my 
permissions are apparently correct (because they're the same as on the 
working machine).

Is there a utility I can use to monitor the /dev/ttyUSB0 device to see 
if anything is happening there?  I've tried "cat /dev/ttyUSB0", but no adeu.

Or does anyone have any other ideas? 

Thanks,
CB
