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.

But Hterm is worth looking into anyway; not only can it use hardware handshaking, it can also go up to 38,400bd (or more) and can translate UTF & ANSII codes. He did mention a 3-wire capable. HTERM won't work. For his 8085 machine TELCOM with XON/XOFF (it the host supports it) may be the ticket. Or just a low baud rate. -- John.
