Problem 3: Connect will not work on COM ports other than COM1 and
COM2.
By default, many PCs are not configured to permit the simultaneous use of
three or more COM ports. Specifically, most PCs are configured such that
COM ports are grouped into pairs: COM1 is paired with COM3, and COM2 is
paired with COM4. By default, such PCs permit only one COM port from each
pair to be operating at the same time (for example, COM1 with COM2). COM
ports within the same pair will usually conflict with one another and are not
supported (that is, COM1 with COM3, or COM2 with COM4).
If you cannot get Connect to work properly on COM3, check if another device
is using COM1 at the same time. Similarly, if you cannot get Connect to work
on COM4, determine if another device is using COM2 at the same time. If so,
you may need to make some changes to your PC configuration to support
using the PassageWay Service Provider on COM3 or COM4. Refer to
Appendix A for more information. If you need additional assistance in setting
up devices on COM ports other than COM1 and COM2, consult your PC
hardware vendor.
Problem 4: Connect occasionally displays its initialization window while
one or more PassageWay applications are running.
Connect displays its initialization window whenever it establishes (or re-
establishes) communication with the telephone. Generally, this window is
displayed only once, at the time when a single PassageWay application is first
executed. However, if a communications problem occurs at any time,
Connect attempts to clear the problem by reinitializing itself, which causes the
initialization window to reappear temporarily. If this occurs while a
PassageWay application is performing a task involving the telephone, the
operation in progress will be aborted and must be restarted manually once
the initialization window disappears. If no task involving the telephone is in
progress during this process, the operation of PassageWay applications is
unaffected.
