Our cash drawer connected to a serially connected Wyse terminal stopped working. I made some changes in the device configurator and wondering if there's a way to restore those.

Any serial cash drawer should work. It's certainly possible that the cash drawer serial port has gone bad or the cable has broken or the AUX port on the Wyse is dead. You should test each of these by swapping this drawer with a working drawer to isolate the problem.

If it's not hardware, the software is wrong. You need to send the transparent print codes followed by the code for the drawer. The TERM variable has to be set correctly to match the emulation the terminal is using. See the debugging section of my article on transparent print as that's likely the problem if nothing else changed.

How do I do Transparent or pass-through printing (slave printing)?

Got something to add? Send me email.
