If you are running a remote application, you should be aware of the following details:
• The subroutines VTSRead and Write will not run on client workstations.
• I/O addresses that are configured only on a client workstation will not be read. They must be committed to the server before they will be used.
• Data blocks are synchronized on startup.
• Switching can occur on RecommendAlternate in order to provide for soft fail-overs.
• Drivers sharing the same serial port must be in the same RPC service. The RPCService variable sets the service name for a driver instance.
