Sending Hex bytes..

VCL TMS Async
1

Hi Guys,

I need to send Hex bytes down a serial port.  e.g. 01 23, 50, FE, 0A

Possibly with a 500ms pause between each.

What is the best way to do this please?

Regards & TIA,

Ian

We'd recommend to write hex values as bytes via vacomm.WriteBuf() 


i.e.
  b: byte;

b := $01;
vacomm.WriteBuf(b,1);

// wait 500ms

b := $23;
vacomm.WriteBuf(b,1);

// wait 500ms

b := $50;
vacomm.WriteBuf(b,1);

// wait 500ms

b := $FE;
vacomm.WriteBuf(b,1);

// wait 500ms

b := $0A;
vacomm.WriteBuf(b,1);

Excellent!  Thanks Bruno.

It seems that this is not working anymore.
tried it on several ways, but it seems that only from $00 - $7F is send (or received)
Want to send $83, but receive $3
