          Setting up the ATI 2400 etc class 5 MNP modem.


     The ATI half-card 2400 baud modem is easy to set up.  Set the
modem switches (on the back of the slot bracket) for your serial port
number, Com 1,2,3 or 4.  Com 1 is the factory setting (default).

Install the modem and start the Setup proceedure for your
communications program.  Enter the following initialization string in
your software program's appropriate place to initialize the modem:

                    AT&C1&D2&B1&K3&Q5S0=0W1&W0

     This string MUST be followed by a carriage return, so it will be
necessary to find out what character your communication program uses
to send a carriage return to the modem, and insert that character
after the &W0 in the string above.  For example, Procomm Plus uses ^M,
and QModem uses {.

     In addition to the above initialization string, it is necessary
to make sure that the modem Hangup string is set as ~~~+++~~~ATH0  and
is similarly followed by the appropriate characters for a carriage
return.  The tilde characters (~~~) and the plus characters in front
of the hangup string create a pause during which the modem will have a
chance to settle any prior activity before resetting itself and
disconnecting.  The tilde character is typed by most keyboards as a
Shift-reverse appostrophy.

     Where changeable, the most important parameters in your
communications software program to set are as follows:

AUTO BAUD DETECT must be set to  -  OFF.
DROP DTR TO HANGUP must be set to  -  YES.
SEND INITIALIZATION STRING IF CD IS HIGH must be set to  -  YES.
SOFTWARE FLOW CONTROL must be set to  -  OFF.
HARDWARE FLOW CONTROL must be set to  -  ON.

     In Procomm, it is necessary to change the Modem Result Messages
for 2400, 4800, 9600 and 19,200 Baud.  Just Delete whatever result
messages are presently entered, and replace them, in capital letters,
with the word:

                       CONNECT

     The next step is to set the Line/Port setup parameter (Alt P in
Procomm) in your communications program to 9600 baud.

     Similarly, set the Baud speed in your dialing directory entries
for 9600 Baud.

     Well, now you're ready to go!
     So,  Happy Modeming!




NOTES:

     Entering AT&V in the communications screen of your program will
cause a display of the active configuration of the modem to appear on
screen, as well as the parameters stored in profiles 0 & 1.

     If it is necessary to resolve connections which are confused by
MNP, you can turn off MNP by entering AT&Q0 in the communications
screen.  Some .
ADDITIONAL ENHANCEMENTS:

     Entering ATL3 in the comunications screen, or adding L3 to the
initialization string above, will set the modem speaker volume to
loud.

     Entering ATS11=50 will in the comunications screen, or adding
S11=50 to the initialization string above, will speed up dialing on a
touch-tone phone.
