6.4 USING THE COMMUNICATIONS INTERFACE PROGRAM’S MONITOR
The Communications Interface program’s primary purpose is to provide data support to the Dispatch Manager program
for the PC-to-CIM serial link and the PC-to-audio system serial link (or PC bus-to-Console Logic Board link if audio system
= Audio Tower). It also has a built-in data monitor. This monitor is beneficial during troubleshooting/diagnostic periods as it
displays receive and transmit link data in a hexadecimal format. Displayed data may also be logged to the hard disk drive in
this same format for diagnostic/troubleshooting purposes. A monitor display with typical data is shown in the following
figure.
