56K Faxmodem Owner’s Manual
NOTE 1: You may find it necessary or helpful to include
S95=44 in your initialization string. This enables
the responses CARRIER (telephone line speed)
and PROTOCOL, as well as CONNECT
(faxmodem-to-computer speed).
NOTE 2: Some software allows these commands to be
added to the list of dial prefixes.
There are other configurations that can be forced as well.
If you need to select a particular configuration, use the
AT command strings shown below. You can always return
to the modem’s default configuration by typing
AT &F
and
pressing the Enter key, but remember that if you do that,
the modem will not have received the commands in your
software’s initialization 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 set-
tings you choose, followed by
&W0
or
&W1
, and press
Enter. For example, if you type
AT &C1 &D2 &W0
and
press Enter, the
&C1
and
&D2
parameter settings are
stored in Profile 0. See Appendix E for the table of AT
commands.)

modem will communicate with-
out any error correction or data
compression, but will retain
speed buffering and auto-speed
negotiation. It should not be
confused with the “standard”
configuration.)
