PROGRAMMING YOUR
SX212 MODEM
u n □□□□□□□□□□□□□□□
The SX212 Modem supports a wide range of programmable
options and S registers. These options and S registers allow
you to change the modem's default settings and customize
its operation to suit your specific communications needs. In
most telecommunications situations, the defaults will not
need to be changed (or can be set using a communications
software program before getting online). However, if you are
writing your own communications program or are using your
modem in nonstandard applications, the options and S regis¬
ters provide the flexibility for increasing the performance of
the SX212 for special uses.
In order to program your modem, you will need to load a
communications software program and enter the local com¬
mand mode so you can communicate directly with your modem.
Once you've loaded your program, you can type and execute the
commands described in this chapter for changing options
and S registers.
Using Programmable Options
Table 2 (on page 22) lists the nine programmable options, their
corresponding defaults, and the range of values that can be
used with each option. An example of how to type in each
command appears in parentheses immediately following the
description of each option's function.
To change the value of any option, follow these steps:
1. Type the attention command AT followed by the letter of
the option and the numeric value you want to set for this
option: for example, ATCO. (The number you type must be
within the range of values supported by the option.)
2. Press [Return] to change the option to the new value. An
OK message tells you the option has been changed.
To reset the modem to its default option settings (and its
default S register settings), type the command ATZ and
press [Return], (You can also reset the modem by turning
it off, then on, and typing AT.)
Note: If you do not enter a numeric value in your command,
the modem sets the value to 0.
