Configuring the Modem
Your modem allows you to tailor its operating parameters to suit your own particular
requirements.
The modem uses S Registers to alter the configuration profile. Each S Register contains a decimal
value to represent a time delay, an ASCII character or the number of times the phone should ring
before the modem answers it (the interpretation of each value differs with each S Register).
The modem allows you to save the contents of the S Registers and certain communication
settings under a profile number (0-3) in non-volatile memory (&Wn). This means the entire
configuration profile will be retained after you have switched your modem off.
The modem also has factory default settings stored internally, allowing you to change the
communication settings and S Register values and then recall the configuration profile stored in
your modem when you originally purchased it.
The factory defaults have been selected so most users will be able to make immediate use of
their modem, without the need to change any S Register values.
You may restore your modem to its factory defaults at any time:
•
Type: AT&F.
There is no need to press ENTER with this command.
Viewing the Current Configuration
The &V command allows you to view the current configuration of your modem. When you issue
the &V command, your modem sends a list of the current AT command and S Register settings
to your computer.
