Warning, this is an arcane problem. From time to time I use an Applied Engineering PC Transporter on an Apple IIGS with PC kermit. The specs for the PC Transporter say it has a V-30 microprocessor running at 4.17 MHZ, a CGA-compatible video controller and 640K dual-port RAM. On the Apple side, for historical reasons I'm still using a SSC and have no problems when I use Apple kermit. I have no problems using pc-kermit 2.29. When I moved up to 2.31 and later 2.32A I find I lose characters at 2400 baud. The character loss occurs only when a terminal is being emulated (not when term is set to "none") and when the screen starts to scroll. It doesn't help to not install ANSI.SYS or a mouse driver that are normally there (I don't know if that steals many cycles or not) and to set display quiet or serial. Protocol transfers work fine -- I've transferred many a large file (100k or more) using 1000 byte packets with nary even a single retransmission. (phone lines here are generally very clean.) Applied Engineering had an upgrade to their software that was claimed to speed up something in its using the Apple communications hardware to emulate the IBM serial ports. I have installed that (and I seem to remember that is what made 2.29 usable.) Suggestions anyone??? TMPLee@Dockmaster.ncsc.mil
