Chapter 3 Solving Common Problems

Note 4:

You may find it necessary or helpful to include

W2 in your initialization string or dialing prefix.
This enables responses that include the mo-
dem-to-modem speed.

Note 5:

Some software allows these commands to be
added to the list of dial prefixes or the initiali-
zation string.

Note 6:

When the protocol is forced, the modem will not
attempt to connect at other protocols if it can-
not connect at the forced protocol. It will try to
connect at the fastest speed available within
the forced protocol.

There are other configurations that can be
forced as well. If you need to select a particular
configuration, use the AT command strings
shown next.

You can always return to the modem’s default
configuration by typing AT &F and pressing the

Enter key. If you do, the modem does not re-
ceive the commands in your software’s initiali-
zation string, as it normally would. Using the

ATZ command overcomes this problem if you
have saved all of your setup parameters in
nonvolatile memory. (To save setup parameters
in nonvolatile memory in AT terminal mode:
Type AT, followed by the parameter settings
you choose, followed by &W, and press Enter.
For example, if you type AT &C1 &D2 &W and
press Enter, the &C1 and &D2 parameter set-
tings are stored in Profile 0.)
