SUMMARY
An asynchronous instance of External may occasionally fail to answer an
incoming call. When this happens, the phone rings several times, the modem
does not go off-hook, and the line is not picked up. The caller will see a
No Answer response to the dial attempt. If the caller attempts a second
call, the call will often go through without any problem.
MORE INFORMATION
External is coded to poll for incoming calls. Thus, External will
periodically check the communications channel for activity. Ordinarily,
External will reach one of these polling points during the rings of an
incoming call, and it will pick up the call.
Slow Network LinksThese factors should be investigated and conditions improved, if possible. If a wide area network is involved, it might be possible to use the DrivesWAN option of External. This is similar to using the DispatchDisable and MailerDisable options, but does not require a second External at the local site. DrivesWAN does require that there be other External programs running at other sites. Also, External will not answer incoming calls while it is updating information from one of the postoffices. Checks for updates occur at regular intervals determined by the IntervalUpdate parameter. An update does not occur at every check, but if changes have been made through the Administrator's program (ADMIN.EXE) or Import program (IMPORT.EXE), then the update takes place. The update interval can be increased so that checks occur less frequently and at more controlled times of the day. Additional query words: 3.20
