I have:
g: The original protocol from the 1970s
G: enhanced g-protocol introduced by Svr4
d: Protocol for DataKit connections.
e: Protocol for TCP links from HDB UUCP, similar to t-protocol.
BSD UUCP used an implementation from Arne Ludwig.
f: Seven Bit protocol with checksums on the entire file at a time
No protocol flow control, but XON/XOFF
It only uses the characters between \040 and \176 (' '..'~')

F: flow control protocol similar to f-protocol.
Written by Piet Beertema, CWI, Amsterdam, Sep 1984
Modified for X.25 by Robert Elz, Melbourne Univ, Mar 1985
Probably created from f-protocol by Carsten Borman TU-Berlin
or by me (Jörg Schilling)
h: A protocol similar to the t-protocol with no error checking.
Apparently used for HST modems.
s: High 's'peed protocol based on the g-protocol.
Variable block sizes 32..4096 bytes, up to 7 windows
Written by me (Jörg Schilling)
t: Protocol for TCP links from BSD
Most likely from Rick Adams
x: Protocol for X.25 links
Jörg
