I'm not sure this is what your wanting, but try this:

aByte := StrToIntDef('123', 0);
{.. Send the Byte ..}

Where aByte = aByte:Byte;
and '123' is the string you want converted to a byte.

I have only tested this in Delphi 3.0 I'm not at my D2 Machine.

I want aByte to have the value 123. 123 is an integer and not a string. It's very important that the value is correct.

Thanks!

It works!!! Thanks! The ASCII tabel I first had was wrong, so I thought that it didn't work.
