where the port specifications inside the Connect command are as follows. Each option takes only one
argument, but they are shown below with the possible arguments separated by “|” with the default value
shown first. The last three options take boolean values that specify which control characters are sent back
and forth to the device indicating when it is ready to get data. Usually, at most, one of these three is used:
Port( "com1:" | "com2:" | "lpt1:" |...),
Baud( 9600 | 4800 | ...),
Data Bits( 8 | 7 ),
Parity( None | Odd | Even ),
Stop Bits( 1 | 0 | 2 ),
DTR_DSR( 0 | 1 ), // DataTerminalReady
RTS_CTS( 0 | 1 ), // RequestToSend/ClearToSend
XON_XOFF( 1 | 0 )
The Port specification is needed if you want to connect; otherwise, the object still works but is not
connected to a data feed.
