[Gambas-user] Serial I/O with byte data

[d4t4full at ...626...]

&H02 is ASCII for STX, a special char that for some protocols mean "start transmission".
Some protocols frame their data payload between chars STX (&H02) and ETX(&H03).
These also normally use some checksum mechanism either before or right after ETX.

Of course it could also be a misleading UTF8 header of some kind resulting from raw data to string conversion, but that I cannot tell for sure.

You need a good protocol manual and check low-level comms frames.
