AT Commands and S-Registers
This chapter provides a list of all AT commands and S-Registers
supported by the KeepInTouch Card modem. This chapter first
lists AT commands in alphabetical order followed by S-Registers
listed in numerical order. Factory settings are listed in bold.
In general, AT commands are responsible for instructing the
modem to do a task, while S-Registers are responsible for
determining how the AT command will perform that task. 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 result code, that displays on your
monitor. Result 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. For
more detailed information on the commands, refer to the help
text file “atcmds.txt” on the Installation Utilities diskette.
The AT commands and S-Registers supported by the
KeepInTouch Card modem are listed in Table 4-1. The
acceptable values for some AT commands and S-Registers
depend on the country in which your are operating your modem.
For those AT Commands and S-Registers, you will be referred
to Table 4-2 for the acceptable values for your country. Table 4-3
also provides command usage information which varies by
country.
