ERROR IN SERIAL COMMUNICATION

[steps]

DEAR SIR,

      HOW TO DEBUG THE ERROR IN VISA (ERROR CODE -1073807330) FOR SERIAL COMMUNICATION WITH PIC MICROCONTROLLER... I HAVE ATTACHED THE PROGRAM ALONG WITH THIS MAIL ... AND THE VISA SOURCE CODE IS COM, BAUD RATE IS 9600, DATA BIT IS 8 ,STOP BIT IS 1,PARITY IS NONE , AND FLOW CONTROL IS NONE.

First, delete your parity control and then right click on the VISA Configure Serial Port's parity input and select 'Create Control'. That will eliminate the coercion. If you still get an error, one by one, remove a property inside the function until the error goes away and you determine which property is causing the error.

What instrument is on the other end and how is it connected?  (I have a sneeking suspicion this is a USB TMC device and most of the serial settings are encapsulated)
