A
modem designed to fit onto the
handset of a
rotary or
touch tone (if you were
lucky then...)
telephone. In the day and age of acoustic
modems,
baud rates were not
speedy and
connections would be
plagued by line noise. &^
Connecting to the
bbs you wanted to
call into
required you to
dial in manually,
listen for a
carrier and then press a button on the
modem. Then, the
handset would be
pushed into the modem's '
cups' and you'd be reading text feeds at a slower than
molasses rate.
