Appendix A - AT Commands and S-Registers

Introduction
AT commands are the means by which you, and your datacomm
software, are able to communicate with and configure your
MultiDSU64K. They enable you to establish, read, and modify
parameters in addition to dialing.
Certain configuration parameters are stored in S-Registers. These
Registers may be read, may be written to directly or may be
modified by other AT Commands.
V.25bis commands provide an alternate set of commands and
responses for applications in which the DTE is synchronous.
V.25bis commands do not include any configuration commands; you
can, however, execute AT/S-Register commands to configure
V.25bis mode operation.
The following sections describe which AT Commands, S-Registers
and V.25bis commands are active in configuring and operating your
MultiDSU64K.
AT Commands
A wide variety of autodial operations and options can be controlled
when the MultiDSU64K is in Command Mode (Switch 14 UP).
Remember, nearly all commands have an AT prefix. These
commands are organized into several functional groups. Options
shown in boldface represent factory defaults.
