S Registers
AT command settings are stored in S-Registers. S-Register values can be changed
by AT commands or by entering the new value of the S Register, preceded by AT.
The command ATSn=v changes register n by setting its value to v.
For example, to change from manual answer to auto-answer after three rings,
follow these steps:
1
Check the S-Register table for the register that controls Answering. The functions
are listed in alphabetical order.
2
Start your communications software and enter Terminal mode.
3
Type ATS0=3 and press Enter. The modem will now answer a call after three rings.
See
SRegisterRef.htm
for a listing of S-Registers and their values.
Result Codes
Modem result codes are messages that appear on your computer screen to inform
you of the status of modem actions or when an error has occurred. What result
codes appear depends on the setting of the ATXn command (see ATXn
ATCommandRef.htm
).
See
ResultCodeRef.htm
for a listing of result codes.
