I have programmed different checksum characters in the past. Now some
device wants a 2 character modula 10,000 checksum for serial
communication.
Can someone give me a hint how to calculate this ??

Thanks in advance !

  REM Initialize
  ' Blah etc.
  DIM FirstChar  AS STRING * 1,
      SecondChar AS STRING * 1

  ' Blah etc.

  CHK = ( ASC( FirstChar ) + 256 * ASC( SecondChar ) ) MOD 10000

...what you are after?

( you might need to swap the + and * signs... )
