Yes, roughly.

Teletype goes way back and starts with speeds of 28.8 bps (I think the 6850 can do that
speed. Newspapers used these machines to deliver stories across the world (WW I, WW II,
etc.). And they're derived from morse code. The ol' time stock tickers are baudot (the
newspapers used various formats like high and low speed tts, baudot and ASCII).

I think when the first modems were being created for microcomputers the common speeds
were 110 and 300 baud
