I simply assert RTS and DTR in my asynch driver and leave them on; I do
not do any form of RTS/CTS flow control. I just don't think it should be
necessary, because TCP does its own end-to-end flow control.  If a
pseudo-full-duplex modem can't spare enough memory to buffer even one
typical TCP window, then that's the modem's problem.

I use V.32 modems (true 9600 bps full duplex) and they work great!
