Operation
The basic commands needed for programming the Modem are provided in
Table
3.
Table
4
lists the dialing and answering commands. For
a
detailed
explanation of each command, refer to Appendix
A,
Command reference.
Commands with parameters
Some of the commands have parameters. The parameter value, usually
0,
1
or
2,
follows the command. When the command parameter is not used,
the Modem assumes
a
value of
0.
For example, the echo command
E
does
not echo when parameter
0
is assumed. It does echo when parameter
1
is
issued.
E
used alone is the same
as
EO.
