When developing a terminal emulator to connect to my college computer
system (around 87/88), we encountered major problems on the input side
if the rate was too high: the buffer in the 2nd processor would
over-run, causing an 11 (if eyes remembers correctly) character delay -
nothing would appear from the SER port and then as each further
character was received, we'd get the 11th previous character (with no
loss); the only cure [we found] being a RESET. We generally used 1200.
I still use the emulator that was written to connect my QL to my other
PC (486, running Dos+Windoze 3.1/FreeBSD Unix) and I find 1200 baud is
the best rate I can manage.
