Save Changes
Saves changes to a option sets made with AT commands.
(If you do not save the changes made with AT
commands, the modem does not store them in nonvola-
tile memory.) After selecting an option set (ATZn; n=0,
1, or 2), and changing options, enter AT&Wn. The
modem displays Saving Options, then Save Completed!.

&X
Clock Signal Source
Sets modem timing. Applies to synchronous
applications. For most dial applications, use option 0.
0
=Internal. The modem uses timing signals passed on
EIA/TIA 232-D Pin 15 (V.24 circuit 114).
1
=External. The modem uses external timing signals
passed on EIA/TIA 232-D Pin 24 (V.24 circuit 113).
2
=Loopback. The modem uses loopback timing signals
passed on EIA/TIA 232-D Pin 17 (V.24 circuit 115).
