Command:
Response:

Status:
Response:

MC SMT_xxxxxxx'cr'
SMT_xxxxxxx'cr''lf']

MC SMT_'cr'
SMT_xxxxxxx'cr''lf']

Where: xxxxxx = IDR, IBS, DI, ASYNC, AUPC, EFD, or
CUSTOM.

Save Modem Config.

Command:
Response:

MC SMC_n'cr'
SMC_n'cr''lf']

Where: n = 1, 2, 3, 4, or 5 (stored configuration number).
This command saves the current modem configuration for
recall at a later time using the 'RMC_' command. Up to five
different modem configurations can be saved.
