How? RS232 HEX & NOT ASCII Tx/Rx

[Ben0]

The Labview serial interface only reads/writes ASCII (which only goes as low
as 20 making it impossible to communicate with our embedded micros under
test) - how can I send/receive HEX??

No, it does binary. As I had to learn not to think of strings as
only the ASCII character set. Take the string character value and
turn it into a byte.

ASCII characters goes from 0 to 127 (7 bit) or 0 to 255 (8 bit).
There are (at least) two ways to easy access all codes:

1:
Set the string control/indicator to show HEX display (or '/' codes
display) (right click on the control).

2:
Convert to/from byte array.
