Multi-Tech Systems, Inc. AT Commands for the MultiModem & SocketModem MT9234 Series (S000434H)
Downloaded from Elcodis.com electronic components distributor
Chapter 1 – AT Commands, S-Registers, and Result Codes
S-Register Control
Use this command to view or change an S-register. S-registers contain parameters
used by the modem. This command has two forms, one to show the contents of the
register and the other to change the contents of the register. Some registers are read
only and are not affected by the S<register number>=<value> command. Each
register has a specific function.
ATS<register number>=<value> Sets the contents of the register to <value> if the
register is not read only.
ATS<register number>? Displays register contents.
None
OK if <register number> is a valid register.
ERROR if <register number> is not a valid register.

Select Tone Dialing

Configures the modem for DTMF (touch-tone) dialing. All subsequent D<dial string>
commands use tone dialing until either the P command or a pulse dial modifier is
received by the modem. Tone dialing is the default setting. This command does not
use parameters and generates an ERROR result code when parameters are
attached to the command.

mode generates result codes as a number. Each result codes has a number
assigned to it.
