This doesn't make sense anyway. We already had 1200 baud modems in the 70s. The *first* commercial modem for computers was the Bell 101 (1958 vintage) and that was 110 baud (quickly succeeded by the 103 at 300baud). I can't think of how 10 baud could've been a thing in the 80s.
Today, the slowest reasonable thing I can think of is FT8, which is 5 bits/sec or so. But that's a ham radio mode designed to use advanced DSP techniques to receive signals many decibels *below* the noise floor, all within a 50Hz bandwidth. Not exactly a thing you code over.
