Appendix 3.
S-PARAMETERS
The supported S-Parameters are summarized in Table A2-1.
Table 3-1. S-Parameter Summary
A3.1 AT=x - Write to Selected S-Parameter
This command writes the value x to the currently selected S-Parameter. An S-Parameter can be selected by
using the ATSn command. All of the S-Parameters will return the OK response if x is a number. Some registers may not
be written due to country specific PTT limitations.
A3.2 AT? - Read Selected S-Parameter
This command reads and displays the selected S-Parameter. An S-Parameter can be selected by using the
ATSn command.
A3.3 Sn - Read/Write S-Parameter
The modem selects an S-Parameter, performs an S-Parameter read or write function, or reports the value of an
S-Parameter.
n Establishes S-Parameter n as the last register accessed.
n=v Sets S-Parameter n to the value v.
n? Reports the value of S-Parameter n.
The parameter n can be omitted, in which case the last S-Parameter accessed will be assumed. The S can be
omitted for AT= and AT?, in which case the last S-Parameter accessed will be assumed.
If the number “n” is beyond the range of the S-Parameters available, the modem will return the ERROR message.
The value“v” is “MOD”ed with 256. If the result is outside the range permitted for a given S-Parameter the values will still
be stored, but functionally the lower and higher limits will be observed. Input and output are always in decimal format.
Note that some S-Parameters are read-only.
In some cases, writing to the S-Parameter will appear to be accepted but the value will not actually be written.
