No one else has mentioned it, but it is worth pointing out that RLOGIN
can be made more efficient than TELNET, since a TELNET implementation
has to look at the data stream looking for IACs, whereas RLOGIN (or
SUPDUP) doesn't. This is not an issue one most unix systems, where
scanning the data stream is not the limiting factor, but it can
make a big difference in a terminal server, where you have (for example)
a poor 68020 trying to deal with 96 terminal lines.
