I haven't tried screen recently, the last time I did it locked the machine
and I had to do a reset button reboot. That was obviously many moons back
up the log. I did try to issue a few ctl+9 type keys, but apparently
minicom intercepts most of them, and I managed to disable much of the
keyboard and had to restart minicom.
Discouraging is what it it. Minicom's vt-102 should be compat, at least I
have for that machine, a vt-102 that works, and a vt-220 that works against
other systems such as a dec pdp-11/23 which expected a vt-220 but when it
smoked its H.O.T. & dec, being their typical selves, wanted nearly 3 grand
for another, then current vt-550 that they wouldn't guarantee I could
configure to be vt-220 compatible, then I re-wrote the vt-102 I had to add
the vt-220 esc codes and used it. The antique machine is a TSR-80 Color
Computer 3, currently running todays version of OS9, called nitros9 because
we've very heavily optimized it to about 2x speed without adjusting the
clock which is married to the video on that hardware.
Are the authors of minicom still available? Or how about src code? I
found some names in the docs and sent an email to those, but it bounced and
that was probably 2 years back up the log.
There are some things that Just Work(TM) and have done so forever, and we
have ID10T's who want to remove the packages for lack of development
activity. Like Procmail. Dumb. And I suppose minicom is also on that
list. More bells and whistles & eye candy, but less true versatility and
functionality seems to be the order of the day for linux. Every time I
upgrade, something that did work, now doesn't.
Anyway, to end this on a positive note, thank you very much, Glynn.
Have a Merry Christmas and a happy, and healthy New Year 2011.
