I think that's a misbelief. Plain 45 Baud Baudot RTTY was still very
common 10 years ago when I was doing short wave radio last time. At least
way more than 100 Baud ASCII or AMTOR. (Actually, the only thing I really
used my ASR-33 ASCII teletyper for was to load/store programs for my AIM65
and ZX81 :)

Things of course may have changed nowadays as nifty little DSP boxes like
the PTC-II took over, first they literally heard the grass growing
(rendering the good old RTTY converters useless cause there's just no way
to give those the same sharp ears) and later allowing fancy stuff like
PSK31 and such.

Really spoiled the hobby, IMO. Buy two boxes, connect them and you're set.
Just like buying 'ham spirit' bottled.
