In the 1979/1980 time frame we were overjoyed at the introduction of
1200 leased line modems connecting our terminals to the PDP-11/70
across town. I was the one who discovered that they would operate
perfectly at 1800 baud -- a 50% increase! The lines were only rated

These days you'd just do it in ROM code in a microprocessor and while
the details of the protocol may be tedious, I'm sure even something
like a lowly PIC microcontroller could keep up with it at 1200 baud.
