Writes an optional string and newline character to the GPS port.
object.WriteLine ( [String] )
- Optional. A String that specifies the text to write.
The parameter "string" is a string specifying the text to write. If omitted, only a newline character is written to the GPS port. The return value contains the number of characters actually written to GPS port. It is the script's responsibility to handle situations where less data was written out to the GPS port than was sent via the WriteLine method.
