C-2.3 Modem Commands
This section describes the menu commands that are available for controlling
Modem operation in the ADFM.
MC - Modem Command
Purpose: Sends a command string to the remote modem.
Format: MC s
Range: s = command string
Description: The MC command is used by the host to send a command
string to the remote Modem (i.e. the one in the ADFM unit).
The ADFM puts its Modem in command mode, sends the
command string, and then sets its Modem back to on-line
mode. This command can be used to send any of the ‘AT’
commands recognized by the ADFM Modem. For example
the sending ‘MC AM0&W0’ to the ADFM will cause the
ADFM to send the string ‘ATM0&W0’ to its Modem. This
string contains two Modem commands: The first, ‘M0’, sets
the Modem to disable its internal speaker, and the second
command, ‘&W0’, causes the currently active internal Modem
parameters to be saved in non-volatile memory (internal to the
Modem), so that the speaker will remain disabled between
power-ups. The ‘AT’ at the beginning of the command string
stands for ‘Attention’, and is required by the Modem to pre-
cede any command, except for additional commands in the
same command line.
MH - Hangup on Ping Start
Purpose: Hangs modem up after the ADFM starts pinging.
Format: MH n
Range: n = 0,1 (0 = no, 1 = yes)
Default: MH1
Description: Use this command to set whether or not the modem hangs up
after the ADFM starts pinging.
MI - Modem Answer Init
Purpose: The MI command is used to set the dial-out interval.
Format: MI
Description: This is the amount of time, in seconds, that should elapse be-
tween scheduled calls that the ADFM makes to the host com-
puter. The syntax for this command is as follows:
