Communications Software
Installation
A personal computer commands and controls a dial
modem through communications software. This software,
which is installed on the PC, uses the A T command set to
send instructions to the modem. A dumb asynchronous
terminal, however, does not require this software since it
can directly send A T commands.
The 3825Plus
can be used with any major
communications software. Refer to your software’ s user ’s
guide for installation procedures. For an overview of how
to use A T commands and a list of AT commands
supported by the 3825Plus, refer to Chapter 4, AT
Command Set and S-Registers .
