The correct syntax (references follow) IS: \r\n
\r = carrage return (CR) \n = line feed (LF)

5.3 Output processing
Regardless of what mode has been negotiated, the server side is
responsible for doing all output processing. Specifically, it should
send "CR LF" when it wants the "newline" function, "CR NUL" when it
wants just a carriage return, and "LF" when it wants just a linefeed.

4.55 13-Apr-97 Fixed extra line problems on MUDs that violate telnet protocol standards
I couldn't find the relevant page, but I remember he went on a bit of
tirade once upon a time about some muds using \n , some using \r and
some using \n\r ..
In the case of the problems reported with the TUSH mud client.. the mud
client is broken and should be fixed. If everyone used the correct
standards then the author of that program probably wouldn't have made
the mistake in the first place...or been forced to violate the standards
to get his/her client working on his/her favorite mud.
Again.. you _must_ use \r\n to be correct with standards, unless you are
negotiating differently via the telnet options with the client. The fact
that some clients/telnet apps allow you to violate the standards doesn't
mean it's an acceptable practice.
