The settings in this worksheet are made via the Project/Communication menu.

Meaning of the individual columns:

drvname

Name (ID) of the communication driver

hostfile

Name of the file (worksheet) with the parameters of the communication channels

nice

Relative priority of the communication task to the RTS task. (0 = equal priority; -1 = higher priority, 1 = lower priority)

The following guideline applies:

drvparam.timeout > Host:Retry * Host:DelayOnError * Host:Timeout
