Sample Televic protocol data

Televic is an extended two-direction protocol, which provides a number of

protocol rules to keep the communication secure; for example, through

sequencing each packet, requesting acknowledge string, handshake

through clear-string, return of feedback on message delivery through what

is called terugmelding string, error detection through checksum, and so on.

Refer to the protocol specifications for details on Televic protocol.

Regarding configuration, the following details are important:

The datastream contains a pager indication. This pager indication is used

as a group indication.

Alarms can either be sent as type 1 (*SET of an alarm that has a *RESET

type 0), type 0 (*RESET of an alarm that was previously *SET through

code 1) and finally a type 2 (*SET of an alarm that does receive a

*RESET). As a result, messages can be *SET or *RESET with remove

after *SENT or remove after *RESET.
