You think it's weird that the Berkeley and Harris versions of talk are
incompatible?  The SunOS 3.5 and SunOS 4.0 versions won't work with
each other (leading to problems in our network where we are
incrementally converting workstations to 4.0)!

Regarding RFC's, the DDN only standardizes the use of ports from 1 to
255.  Any port number greater than 255 is not under the control of a
DDN standard.
