I had been having intermittent problems making dialout connections on a
Unixware 1.1.3 machine, running 5a-189 C-Kermit. Occasionally, a
connection wouldn't echo any keystrokes, although I could see TX data going
out.
I discovered that Unixware is rather untidy about the handling of RTS.
If RTS isn't asserted, my modem won't send any data to the system, which is
correct, but annoying.
I am using the "hardware" port /dev/term/01h.
If I use the "soft" port, /dev/term/01s, then the connection is okay, but
without hardware flow control.
If I run my macro "mmodem" a few times, each of the commands toggles DTR,
and magically, on one of the toggles, RTS is asserted.
I assume that Kermit is doing the correct thing, as usual, so I am looking
for some way to kick Unixware in the right spot.
define mmodem set modem hayes,set line /dev/term/01h,set speed 38400
I think for now I will set a macro "start", that will call mmodem three
times, which always seems to work.
