WRITING APPLICATIONS THAT USE 6100 MPS-B

Enable Noncontinuous Polling

This form of the request is used to begin noncontinuous polling

of the stations in the Poll/Select list. You can include a value

that defines the number of times you wish to traverse the Poll

list. Once begun, polling continues for the specified number of

passes through the polling list until either a station responds

to the poll with a message, or an error occurs.

The request buffer format is:

Function := 68

Modifier := 2

Request ID := A unique value from 1 to 32767,

application-dependent

Text Out := 2

Text In := 0

Text := A value defining the number of times to traverse

the Poll list (2 bytes)

The response buffer format is:

Function := 68

Status := 0 if the operation completed successfully, or

a code greater than zero if an error occurred

Request ID := The same as in the request

Text Out := 0

Text In := 0, or

2 if status detail code is present in Text field

Text := Null, or

Byte 0 = status detail code; Byte 1 = 0
