We are working on switching our POS registers to Ubuntu from Windows. Our registers run in a WAN configuration so the POS software doesn't actually run on them but rather is running on a Windows server and is served to them through Citrix Receiver. We have our devices set in the POS software on the server to specific COM ports. When a register connects the server maps up the COM ports/devices on that machine and talks to those devices on specific COM ports. Specifically COM4 for receipt printer and COM5 for credit card reader. Both are USB devices emulating COM ports.
I've already made the user part of the dialout group and found the tty devices in the /dev folder.
What do I need to do tell ttyAMC0 to identify itself as COM5?
