My principal use of MS-Kermit is indeed for connecting to UNIX systems. And
indeed I usually use ixon -ixoff ixany. But I've tried your advice now, and
it didn't help at all.

I made some more extensive tests, and found that Kermit starts beeping and
loosing characters almost immediately when I type anything while output is
going on to the screen, but starts emitting xoff:s much later. (I do have
flow control set to xon/xoff in Kermit.)

I even loose characters when there are less-than-one-line bursts of output
with pauses inbetween (and I type heavily), in which case Kermit couldn't
possibly need flow control.

I really wonder why Kermit beeps. It can't just beep by accident. It should
meen something.
