In addition to the speed, are the protocols the same?
For example, if you were to just slow down a Bell 212 (1200 bps) modem to
300 bts per second while still using the same frequencies and encoding,
that would NOT enable a Bell 103 to be able to communicate. It would ALSO
be necessary to switch the encoding to a FSK using the Bell 103
frequencies.
I could certainly feed 10 characters per second through a V.90.
But that would NOT provide the CCITT V.18? protocol needed for most 110
baud devices.
