I sped up my copy of Pcomm about 7-fold (I use it with a TB+) just by changing input.c to read up to 100 characters at a time, and then echoing them in a more efficient manner. The output is a little bursty, but it can repaint a screen in less than 1 second at 9600 bps. -- Karl Fox, Morning Star Technologies ...!{att,osu-cis,pyramid}!mstar!karl
