Appendix G: Result Codes
The table of results codes below indicates the verification
messages that the modem generates depending on the
currently active Xn option. The default setting is X4. To
select short form messages, enter the command
AT V0. To
select long form messages, enter the command AT V1. The
default setting is V1.
A check in a column indicates that the message is
generated by the modem when you have chosen the value
shown at the top of the column with ATXn command. If
the column is blank, the modem does not generate a
message for that X option. A “
1
” or “
3
” after a check mark
indicates the less explicit message that the modem
generates for that option. For example, if the modem is
set for long form messages, the value of Xn is X0, and the
computer-to-modem speed is 1200 bps, the modem
generates the message “CONNECT” and not “CONNECT
1200”.
