Using an USB port as a standard DB9 Serial Port
 

I've been using the DB9 serial ports to run Wyse 55's as cash registers, and now I need to start using the USB ports. I got a USB to Serial converter with a DB9 end to plug in the connector and cable to the Wyse 55.

Since I found ttyUSB0 in /dev , I tried to dump to the Wyse 55 and only got "0mtotal 178" on the Wyse when I did:
ls -l >/dev/ttyUSB0 or
ls -l >/dev/usb/ttyUSB0

Then I tried to setup the entry in /etc/inittab as follows:
S0:2345:respawn:/sbin/agetty ttyUSB0 -L 9600 wy30

I have no idea what to do next.
