from the modem of the other party.

ignored and the modem operates as if the ATNO is inputted.

determined by the S37 value. In addition, you should select communication standards of CCITT
and BELL with the ATB command.

automatic detection function. At this time, the ATB command is ignored and only CCITT mode is

If the modem is in the state of command, it is converted to the online status by the Escape Code

converting to the data mode by the ATO command without disconnection.
