AT Commands and S-Registers
This chapter provides a list of all AT commands and S-Registers
supported by the KeepInTouch PCMCIA modem.
In general, AT commands are responsible for instructing the
modem to do a task, such as dialing, hanging-up, loading factory
default settings, etc. However, some AT commands, and most
S-Registers, are responsible for setting configuration options
which determine
how the modem operates. You issue these
commands to your modem via your communications software.
When a modem receives a command, it responds with a
message, known as a response code, that displays on your
monitor. Response codes are described in Appendix C.
For a brief overview of command guidelines, refer to the
Using
AT Commands section in Chapter 3, Using Your Modem.
The AT commands supported by the modem are described in
Table 4-1. S-Registers are described in Table 4-2, which begins
on page 4-20. Factory settings are listed in bold.
NOTE:
Use only those commands and S-Registers that are
described in this chapter. Entry of any other commands or
S-Registers is not supported and may produce
unpredictable results.
