The _modems_ are the Bell 103 style and are compatible with the
300 baud signalling of 300/1200/2400 baud modems.  The character
set is 5 bit baudot which uses the SI/SO characters to get 64
characters into the character set.  Baudot isn't very much like
ASCII and it's upper case only as I recall.

Some smart modems won't accept or send data at 50 Baud because
they look at the serial bit stream (+++) for command information.
