S-registers
S-registers contain the settings that determine how a number of functions of the
internal modem operate. For example, how many times to let the telephone ring
before the modem answers and how long to wait before it hangs up if a connec-
tion fails. You can also customize certain AT commands such as the escape
sequence and command line termination.
The contents of the registers are changed automatically when you modify
corresponding settings in your communication software. If you choose,
however, you can display and edit the contents of the registers manually when
the modem is in command mode. If the value is out of the acceptable range, then
an error is generated.
This chapter describes the settings for each S-register.
S-register values
The format for displaying the value of an S-register is:
ATSn?
where n is the register number. After you type in the register press Enter.
The format for modifying the value of an S-register is:
ATSn=r
where n is the register number, and r is the new register value. After you type in
the register and its new value press Enter.
NOTE: Some registers vary from one country/region to another.
