Appendix B: PC Serial Ports
Given the scenario described in item (1) above (that is, a mouse on COM1 a
fax/modem card on COM2, and PassageWay Solution on COM3), you might
buy a bus mouse and configure it to use, say, IRQ2 or IRQ5. This would then
permit you to move PassageWay Solution onto COM1 (IRQ4), where it could
then be used simultaneously with both the mouse and the fax/modem.
Likely candidates for conversion from a serial interface to some other interface
include mice (which can be converted to...

Appendix B: PC Serial Ports
Windows to monitor IRQ5 rather than IRQ4 for the COM3 serial port – this is
accomplished using the Windows Control Panel under the Ports option (see
your Windows documentation for details).
If you attempt this solution, you must be certain that you do not choose an IRQ
which is in use by some other device in your system – if so, you will only trade
one type of IRQ conflict for another. You should be aware that many common
add-in cards use IRQs, including network cards and...

Selecting an Add-In Serial Port Card
This section presents advice on how to choose an add-in serial port card for
use with PassageWay Solution. Because PassageWay Solution does not have
any unique requirements with respect to serial ports, this advice applies
generically to selecting a serial port for use with any peripheral.
In general, there are two main things to consider when selecting a serial port
for use with PassageWay Solution:
1.Choose a card which offers the...

Appendix B: PC Serial Ports
PassageWay Solution operates at a relatively high data rate (19.2 kbps,
or 19200 baud), and it relies on Windows to manage the flow of data
through your PC’s serial port. Depending upon your configuration,
Windows may have problems maintaining high data rates through
traditional serial ports. In these situations, a serial port designed for
high-speed communications can eliminate such problems while
providing a reduced load on the microprocessor (thus increasing the
performance...

Appendix C: Running AT&TBuzz
in Export via Paste Link DDE Mode
The Microsoft Windows operating system provides the Dynamic Data
Exchange (DDE) method for transferring data between applications. One form
of DDE supports a registered clipboard format called Link. When associated
with the application’s Copy and Paste Link commands, the Link clipboard
format allows the user to establish DDE conversations between applications by
copying a data item in one application and paste linking it into the other....

where:
nhandle is an integer that refers to the handle of the telephone call.
ncaller id is the telephone number of the calling party.
nline label is the label of the line that the call came in on.
ncall origin info is the complete call origin string. For PARTNER systems,
the call origin info is identical to the caller id.
A macro should be written in the other application to parse the string when it is
received. It may want to look up the...
