ATQ0

Disable quiet mode (result codes are sent to the MAS) (default)

ATQ1

There are some low intelligence devices (often found when retrofitting CDPD to a landline or
radio based system) that cannot accept any result codes. Q1 is an appropriate setting for that class
of device.

Result codes:

If ATQ1 selected; OK response is suppressed

If ATQ0 selected

Select Register

Selects a register for interrogation or modification in the current active profile. Subsequent reads or
writes to the register are accomplished with the ? or = commands, respectively. The S command is
normally used with an appended ? or = . The register remains selected until the next ATS command.
The complete set of S-Registers is described in Appendix E.
