Chapter 17 - Status Registers and Result Codes
S-registers (Status Registers) contain values that determine and reflect how your Terminal
Adapter (TA) operates and executes commands. You can read the values and change
them, either using terminal commands or the modem's panel controls with the same
results.
Every user profile corresponds to a separate set of S-register values, but when we
mention S-registers, we are referring to the ones that correspond to the active profile. If
you want to read or change the values in a profile that is currently inactive, you will first
have to recall that profile to make it active.
At the time this manual was written, Omni TA128 was equipped with 124 S-registers,
from S0 to S124. S0 to S11 are standard AT S-registers, and S12 to S124 are mostly bit-
map configured. Changes in the bit-map configuration can have the same effect as issuing
AT Commands. However, it is recommended to use equivalent AT Commands.

Viewing and Setting S-Registers

There are several AT Commands that are used to view the values stored in the S-
registers.
Viewing S-registers
To display the value stored in S-register 'r' with AT Commands, use:
ATSr?
To view all of the S-resister settings use the &Vn command:
AT&Vn
View S-register settings for current active
n=0
profile
n=1-4
View settings for user profile number (n-1)
n=5
View the factory default settings
n=6
View the analog adapter's setting, Phone 1
n=7 View the analog adapter's setting, Phone 2
The S-register values may be displayed in either Decimal or Hexadecimal format when
using the preceding commands. Bit 3 of S-register 84 sets which numbering system is
used for display.
ATS84.3=0 (for decimal format)
ATS84.3=0 (for Hex format)
To display the value of bit b of S-register r, type:
ATSr.b?
