Of course, > the rwin parameter in config.tel has no effect if you're using MacTCP. I wonder if this is in any way related to the extremely slow performance we get with Telnet. We run NCSA Telnet 2.4 and 2.5 on Mac-IIci's running 7.0.1 w/ MaTCP 1.1 or 1.1.1 on a relatively lightly loaded thin ether segment. Telnetting to an otherwise idle Ultrix box sitting right next to my Mac, I get performance (for big blocks of text, full screen updates in a 40-line window) that seems to me to be about on a par with a 9600 bps connection. Currently, I'm at home running kermit (also with a 40-line screen size) over a 19.2 V.32bis connection to a terminal server telnetting to that same Ultrix box through GOK how many bridges, repeaters, etc and getting performance which is about as good. -- Roy Smith <roy@nyu.edu> Hippocrates Project, Department of Microbiology, Coles 202 NYU School of Medicine, 550 First Avenue, New York, NY 10016 "This never happened to Bart Simpson."
