I have a HP9000/520 running HP-UX 5.21 and a Telebit T-1000 9600 baud modem. I use the modem to dial in to a SUN-4 network with a Telebit Trailblazer modem. Things are set up so that when I dial in (using cu) the connection is in PEP mode (as indicated by the FST light) and I can cat a file from the SUN to my HP screen at about 6500 "baud". (All the "baud" rates are calculated as numer of characters times 8 divided by transmission time). So far so good, but we need a way to transfer rather large files (say 350k characters) from one system to the other (with error correction) at a rate close to 9600 baud. In the past, to another machine, over a direct line we've successfully used the HP-UX kermit. However, when I try this over the modem to the SUN, kermit seems to execute normally but the effective "baud" rate is about five hundred (500). A suggestion has been made that maybe the kermit packet size is too small. However, the kermit(1) documentation doesn't seem to give a way to twiddle packet size. I'm planning to bring up UUCP but are there any assurances that the transfer rate will be higher? Any suggestions? Tim Sullivan tss@lanl.gov CNLS/P-10 MS B258 LANL Los Alamos, NM 87545
