Table 3-13:
Q<value> Commands
S<register_number>=<value>—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 one 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. See “S-Registers” on page 84.
Result codes:
OK if <register number> is a valid register (see Table 5-3: S-Register Summary).
ERROR if <register number> is not a valid register.
Table 3-14: S<register_number> Extended Syntax Commands
T—Select Tone Dialing
Use this command to configure the modem for DTMF 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. Do not
supply parameters with this command unless it is used as part of a dial modifier.
V<value>—DCE Response Format
The 56K Softmodem generate result codes using one of two formats. Verbose
mode generates result codes in a text format using words. Numerical mode
generates result codes as a number. Each result code has a number assigned to
it (see “Result Codes” on page 81). Use this command to switch between
numerical and verbose modes. Call progress and negotiation progress messages
are affected by this command.
Command Function
Q0 Enables result codes (default).
Q1 Disables result codes.
Syntax Function
S<register_number>? Displays register contents.
S<register_number>=<value> Sets the contents of the register to <value> if the register is not read
only.
