Protocol Capabilities
The TINET multipoint supervisor protocol conforms to the poll and select protocol
described under the heading "Host Communications" in the Texas Instruments Numeric
Entry Terminal Characteristics Guide. The protocol provides the following capabilities:
•
Check-character generation and verification
•
Retries of operations in error
•
Timeouts on all line operations
•
Support for the message formats shown in Table 8-1.
