A fair while ago I noted that MSKermit 2.32 (or thereabouts) was losing
characters when run on an Applied Engineering PC Transporter plugged
into an Apple IIGS.  Somewhat by accident I just discovered how to solve
the problem.  I had been using the Apple Super Serial Card to drive the
modem.  (No reason to change, right, when I moved up to the GS?)  for
entirely unrelated reasons I decided to get the right kind of cable and
connect the modem to the GS's built-in serial port rather than to the
SSC, and reconfigure the PC Transporter's drivers to use that to emulate
COM1.  Lo and behold, nary a character lost.  (Oh yes, key point, I
think:  I set the Apple serial port up with buffering enabled.)
Conclusion:  the Applied Engineering serial card driver either a) does
not use interrupts, or b) doesn't have a big enough buffer.
