when a connection is established.

For example, if you have X1 set, you may see a response
message such as “CONNECT 57600”. If you have X5 set,
however, the response for that same connection (if error control
is used) would be “CONNECT 28800/REL”. (REL is short for
“reliable.”) Or, if you have X6 set, the response may be
“CONNECT 28800/V42bis” (if you are using V.42bis data
compression).
The possible protocols which may be appended to the
CONNECT response are:
G
V42
G
V42bis
G
MNP1

MNP2

MNP3

MNP4
