Subject: Re: C-128 CP/M screen I/O
Using the public domain CONF command to set the RS-232 baud rate to a very
low value helps a great deal. (Of course, when you use a terminal program,
it's reset to something reasonable). CP/M's lowest baud rate setting is
50bps, but at that rate it drops keystrokes. Two settings that provide
adequate key scanning while improving performance markedly are "conf
baud=110" and "conf baud=75,feel=0". I'm not sure exactly what "feel" does
but the lower the (non-negative) value, the better the keyboard's response.
It would be interesting to see some kind of comparative benchmark of these
2 settings. Based on a subjective and unscientific test (scrolling in VDE),
the 110bps setting seemed slightly faster, contrary to What Should Happen
(tm). (or what intuition would suggest.)
