You can use "MMTTY" and "RTTY terminal" under WINE in linux.
The two in combo will do what you desire.
You will need to configure the Windows COM port in WINE to your linux port. But that is about the most difficult thing to do,
I use Ubuntu

Hello, is there an (ideally linux) program that converts ITTY to ascii for convenient streaming to my model 33 via RS232?

My 3 year old likes the teletype a lot, so telling him that it is printing updates from people far away would blow his mind.

Thanks!
