They do block, but the driver still processes an interrupt every 16
characters or so. At 50k compressed to 100k, that's 6250 interrupts per
second. Not a vast number by today's standards, but enough to be
noticed.

It was a claim by a guy from Lucent who says he's used their modem on a
486. Not standard marketing, but maybe a bit biased; who knows.
