Communication appears to work with 9600 baud, 8,N,1, (and XON/OFF) in both directions - for a short time.

After a few hundred (?) characters, sending from the Rainbow to Putty stops (in terminal mode T). A handshake problem?

Must admit i haven't checked out Edstrom's recent changes...

It would be nice if other bitrates than 9600 were possible. I heard the VT100 terminal emu works best at 4800 bps (given the slow main CPU, clocked at 4,81 Mhz).
