Aloha POS integrate with Fosse PMS 1

[FnBGirl]

Connected to Fosse (Marriott) PMS server with serial null cable. Communication is fine. Able to inquire, but unable to post to the room without FOH bombing "Invalid argument was encountered." Nothing seen in debout. Unable to post in BOH either.
Baud rates, bits and parity came straight from Marriott PMS support.
Any suggestions would be helpful.
TIA

just quit working. How many terminals and do they all respond the same.

I would reinstall the terminal and or upgrade aloha.

Cheers,
