I timed our HDS terminals by doing something like
(first set no flow control in the terminal's setup mode)
csh% set time
csh% cat /etc/termcap
on an unloaded system and then dividing the size of /etc/termcap by the
elapsed clock time. The HDS 200 came out to something like 480 chars/sec
(4800 bps) or somewhat faster, but definitely not able to do 9600 bps. The
newer HDS 2000 came out to roughly 960 chars/sec or better, but unable to do
19200 bps. There were some (non-HDS) terminals we looked at that could really
do 19200 bps ... I only wish our tty-lines and tcp/ip terminal servers could
handle 38400 bps, so I could have tried them at that speed!
