BinaryCrossCheck = BCC

[bronco3456]

Hello!
I´ve checked the files, but could not find anything helpfull regarding the BCC in a serial communication.
For the device I am trying to access it is vital to have the BCC of the characters included in the string to send.
The BCC is done by an XOR of the characters to be send. I could not find any solution in the boards.
The next question concerns VISA the character format should be in my case: 
1 start bit + 7 bit ASCII data + 1 parity + 1 stop bit = 10 bits
So far so good, do I have to create the  start by myself in the string or is there a possibility in VISA
to force the device to generate the necessary start bit. Greatful for any help!

Here is how to XOR all chars of a string.



The start/stop/parity bits are generated automatically by the hardware.
