APPENDIX A: AT COMMAND SET

This appendix contains an explanation of each AT command accepted by the 7400B Data Module. Labels used in the descriptions are defined as follows:

LabelDescription

Command:The command is shown as it should be typed. The command may be typed in uppercase or lowercase. Spaces may be typed between multiple commands on the same command line for readability, but the spaces are ignored by the 7400B Data Module.

Function:A brief, functional description of the command is provided here.

Type:Type may be immediate or configuration. An immediate command causes the data module to perform an action as soon as the command is sent (for example, go off-hook or dial a number). A configuration command modifies a configuration parameter during the current session.

Arguments:Many commands accept or require a numerical argument. Whether an argument is required and the range of acceptable values for the argument is shown here.

S-Register:The S-registers consist of 28 1-byte memory locations in the data module, designated as S0 through S27. The S-registers hold values for defining the current configuration of the data module. Some commands modify a specific S-register, and some commands perform an action based on the current value stored in an S-register. Whether an S-register is modified or read by the current command is explained here.
