Using ENQ handshaking |
|
The enquiry (ENQ) byte, hex value 0x05, can be used by a PMS protocol in one of two ways:
By default, this setting is disabled. When the hospitality server needs to send a message packet to the PMS, such as when sending a maid status update, it will just send the message; it will not send the enquiry byte first.
To enable (or disable) having the hospitality server send an ENQ byte and wait for an ACK each time it wants to send a message to the PMS, follow these steps:
1. Using Activity Monitor, stop the voice mail service.
2. Run the System Configuration application and select Features | Hospitality.
3. If prompted, select the PMS instance (as shown below). This dialog is only displayed if you are licensed for more than one PMS instance. Otherwise, skip to step 4.
4a. If the PMS connection is over a serial link, select the Serial settings property page (in the tree view on the left). Then skip to step 5.
4b. If the PMS connection is over a TCP link, select the TCP/IP settings property page (in the tree view on the left).
5. Check the Use ENQ-ACK handshake box to enable the feature (or uncheck it to disable the feature). 6. Click Apply to save the setting without closing the dialog. 7. If you are finished configuring hospitality settings, click OK to save and close the dialog. 8. Once you are finished with all configuration changes, close System Configuration. 9. Using Activity Monitor, restart the voice mail service.
