RS-423 however.  This EIA specification is for data generators and receivers
only (just as RS 422 is) and should not be construed as a replacement
for RS-232.  In fact RS 423 generated signals can work with RS-232 interfaces.
The EIA spec for RS-449 is the valid spec for comparison with RS-232.  It
provides for the use of either RS-422 (balanced transmission) or RS-423
(unbalanced transmission).  The maximum data rates with RS-423 are similar to
those of RS-232 interfaces while the maximum data rates with RS-422 are
about 1 Mbit/s (depending on distance).
