to the modem’s manual for the command set used by the modem
installed at the PC. Note that most modems (although not
necessarily manufactured by Hayes, US Robotics, or Zoom) can
utilize one of these three configurations.
Clicking on the Modem list box and selecting the desired modem will
automatically configure the various modem parameters to meet
most User’s needs.
If a modem with a command set different from the supplied three is
used, a custom Modem Type entry can be added to the Modem list
box. To enter a custom Modem Type, the Dial Prefix, Hangup
command, and Initialization strings need to be added. Refer to the
User’s manual supplied with your modem and follow these steps to
add a custom Modem Type entry:
1. Click on the Modem list box arrow and enter a new
Modem configuration name.
2. Edit the Dial Prefix text box with the command required
by your modem. Upon commencing of dialing, this
Prefix string is sent immediately before the phone
number. For most modems this will be ATDT (if touch-
tone dialing is supported by the phone line) or ATDP (for
pulse dialing on phone lines not supporting touch-tones)
3. Edit the Hangup text box for the requirements of your
modem. Nearly all modems will use ATH. The Hangup
string is transmitted to the modem when the User clicks
on the Hangup button from within the Modem
Communications dialog.
4. Edit the Initialization text box for your modem’s
requirements. A multitude of variations are possible for
this initialization string and the modem User’s manual
should be referenced carefully. The initialization string is
sent to the modem immediately after clicking on the Dial
button within the Modem Communication dialog. Key
parameters to specify in the modem initialization string
include:
Ρ Verbal Response codes ENABLED
Ρ Full Response code set ENABLED (eg Busy,
Connect 14400/ARQ, etc)
Ρ Echo DISABLED (off)
5. Clicking on the OK button saves the three strings to the
Modem Type name specified in the Modem list box.
After configuring all modem parameters, click on DIAL and the modem
connection sequence will commence. After a short dialing and
communication protocol negotiation between the modems, a dialog box will
show indicating success or failure in making the link.
If successful, click OK . Close the S ERIAL C OMMUNICATIONS dialog box with
another OK and HyperWare will return to the H YPER C OMM window ready for
communication.
If the link fails, check the following points:
