6. Disconnect the call using the options in your software pro¬
gram or by issuing the appropriate modem command (see
Using Modem Commands
below). The OH (Off Hook) and
CD (Carrier Detect) lights will go off. (You can also discon¬
nect the call by turning your modem off.)
In addition to dialing calls, your SX212 is also capable of auto¬
matically answering a call. See your software user's guide for
instructions on using this feature.
Using Modem Commands
After you've loaded your communications software program, you
can operate your modem by typing commands rather than using
the program options. Entering commands in the terminal or local
command mode allows you to communicate directly with your
modem before, after, and even during online communication.
Table 1
(on page 16) includes a complete list of all the dialing
and operating commands supported by your SX212 Modem,
with an example in parentheses of how to type them in. (See
Chapter 3, Programming Your SX212 Modem,
for information
on the programming commands.)
The sections that follow describe how to use these commands
to dial, answer, and disconnect a call and to perform other
communications functions.
Dialing a Call
1. Load your communications software program.
2.
Make sure your modem is turned on and the MR (Modem
Ready) and TR (Terminal Ready) lights are on.
3.
If you are using tone dialing, type ATDT in uppercase letters.
If you are using pulse (rotary) dialing, type ATDP in uppercase
letters. On the same line immediately following the command,
type your telephone access number (up to 38 characters)
with or without punctuation. (For example' ATDT5551212.)
If you make a mistake, press
[Backspace]
to erase one
character at a time. Then press
[Return],
You should hear the progress of your call through the modem's
speaker if the volume level is set.
