Recap: Kermit 3.14 is unable to drive the built-in modem of my Tecra
740 above 2400 baud. I've since found that it works ok at 4800, but
definitely locks up at anything faster.

The Tecra 740 is Toshiba's top-of-the-line laptop. It's the size and
weight of the San Francisco phone book, and gets hot enough to fry
eggs. It's also faster than the Sparc 20 in my office. I think the
speed may be a significant factor.
Joe's suggestions focussed on the modem, but that doesn't explain why
I get the same behavior with an external modem on a regular com port,
nor why Kermit 2.29 works fine with the same modem.
I've since done some further experiments using a Toshiba Portege 660
(150 MHz Pentium). This produces identical behavior to the 740:
Kermit 2.29 works fine, 3.14 locks up above 4800 baud.
The 660 has Linux, so I tried C-Kermit and that also worked perfectly.
My speculation: these machines are *very* fast; I also remember
reading somewhere that the highly integrated chipsets of these laptops
run the UART (which is the FIFO variety) at full bus speed. So maybe
the lean-and-mean 2.29 and the moderately trim C-kermit can keep up
whereas 3.14 cannot.
Is this plausible? Can anything be done?
