Programming

Open the Settings menu, select Modem Commands, set the following parameters:
Dial Prefix = ATDT
Dial Suffix = ,,,,,12748
Hangup prefix = +++
Hangup suffix = ATH
Modem defaults = Hayes for most modems
These parameters set up how your modem dials a phone number and how it hangs up the phone line.
Open the Settings menu, select Phone Number, make the following entries:
Dial = the phone number for the line to the Model 748
Time out = 45 seconds
Open the File menu, select Save As, and enter a file name. This will save the configuration,
complete with phone number and password, for this site.
You should now be setup to call a Model 748 at 2400 baud, using the default password. You are also
setup for file transfers as required.
CONNECTING:
Open the Phone menu and select Dial. This will dial up the Model 748, pause 10 seconds, and send
the program access code. You may need to add or subtract a “,” (comma) in the Dial suffix string to
get the timing correct.
A pop-up window will appear indicating we are trying to connect to a modem, a timer will be
counting down. You will also be able to hear the progression of the call. Once the modems have
connected you will see “CONNECT 2400” indicating a successful connection with the Model 748.
Press the
ENTER
key (or
RETURN
key) and you will be presented with the Main Menu in the Model
748.
To perform a file transfer with the Model 748, you must first initiate the file transfer in the Model
748. This is done in the Accounting menu. You then open the Transfers menu in Terminal and select
either Receive Binary File, or Send Binary File, and then select a file name. The bar on bottom of the
window will give status information on the file transfer. Note that once a download from the Model
748 has been started, it will take up to 20 seconds for the two machines to agree to start the transfer.
This is normal. The Model 748 supports Xmodem (checksum).
