Ok, here's the problem: I'm trying to find a modem/terminal program for my //e that can keep up with a Trailblazer 2500 running V.32, V.42, V.42bis. I'd be happy with a program that can cope with 19.2k bps, though burst speed occasionally exceeds this. Decent VT100 emulation is desirable, but I can live with VT52. So far, I've had the most luck with Ascii Express Mousetalk, probably because it uses polling rather than interrupts to talk to the serial card (which is an Applied Engineering SerialPro; it acts like an ordinary Super Serial card). I have a 4mhz ZipChip -- the modem was useless without it. Would an 8mhz ZipChip help, or is the bottleneck somewhere else? Also, do there exist serial cards with hardware handshaking, and if so, are there terminal programs that know how to use them? Thanks for any suggestions, Mitch trott@dolores.stanford.edu

OK, with an 8mhz Zip, I'm sure that most of your problems would be solved. Using a terminal program that uses interrupts is much more reliable in general; at 8mhz the interrupt overhead imposed by prodos wouldn't amount to much and may be able to use 19.2 (think of it this way - the GS runs at 2.8mhz, and the interrupt overhead was eliminated in the serial firmware allowing the GS to use Appletalk which runs at about 210kbaud). Now, as for programs to use: Most are here are fans of Proterm which can be had for somewhere between $60 and $95 depending on where you shop. There's my Z-Link, which is shareware for $25. Finally, there's Kermit which is free. All of these support vt100 and vt52, various file transfers, and so on. I'm biased (duh) but I like Z-Link of course. If you get Z-Link, then you have access to instant customer support (through e-mail to me). You can also reach the authors of Kermit thru e-mail. There must be other programs for the //e, but I can't remember (is TIC //e or //GS?) -- Dave Whitney Computer Science MIT 1990 | I wrote Z-Link and BinSCII.
