Thanks for the responses, guys. In fact, the 8085 SBC is capable of CTS/RTS but the RTS signal is not connected to the serial cable. I will have to figure out how to crimp an extra wire onto the molex connector, and use a slow baudrate in the mean time.
I'll also say that I'm interested in the REXCPM and MTVGA protects that are in the works :) - Andrew On Wed, Feb 20, 2019, 2:27 PM Mike Stein <mhs.stein at gmail.com> wrote: > Glitch's SBC does have a 5-pin RS-232 connector so maybe hardware handshaking > is an option with an appropriate cable? > > If hardware handshaking is available then AFAIK Hterm will work up to > 38,400bd with a 5-wire cable. > > If H/W handshaking is not available but XON/XOFF is then Telcom will work > fine up to 19,200bd with a three-wire null modem cable. > > If neither handshake version is available then indeed, you'll have to limit > yourself to a low baud rate, probably 1200 or less, to avoid buffer overflow; > presumably Hterm could still be useful in this case for its conversion > feature. > > m > ----- Original Message ----- > From: John R.
