  Ascii / Hex
  
  send_string dvZpre1,"'W 1 1 1',13" :
  
  'W 1 1 1' thats an ASCII String
  ,13 thats an CR in DEC
  
  send_string dvZpre1,"'$57,$20,$31,$20,$31,$20,$31',13" :
  
  '$57,$20,$31,$20,$31,$20,$31' thats a HEX Command as an ASCII String...
  try without ' ' (Highcomma)
  i think thats should be work !
  send_string dvZpre1,"$57,$20,$31,$20,$31,$20,$31,13"

  I have some problem with
  DEFINE_CALL 'SWT_KRAMER' (INPUT,OUTPUT)
  {
  IF ((INPUT >= 0) AND (INPUT <= 8) AND (OUTPUT >= 0) AND (OUTPUT <= 8))
  {
  SEND_STRING dvKramer,"$01,'$',ITOA(INPUT + 80),'$',ITOA(OUTPUT + 80),$81,$0D"
  }
  }
  
  What i do wrong ?

  You need $80 not 80

  I'm confused. You do know that $ is not the actual ascii character '$' right? the $ is just a sigil that signifies the following two numbers refer to a hexadecimal number. For instance $FF = 255.
  
  Oh and you're converting your additions to ASCII with ITOA(). You don't want ACSII characters. You want numbers. Try this: SEND_STRING dvKramer,"$01,(INPUT + $80),(OUTPUT + $80),$81,$0D"

  This one works for me,but it does create this compiler warning:
  
  C10573: String used as a CHAR value in a math operation
  
  
  send_string dvvidswitch,"$01,(80+itohex(input)),(80+itohex(output)),$81"

  itohex() produces a 2+ character string with ascii characters representing a value. For instance itohex(255) = 'FF', itohex(256) = '100', etc.
  
  it's useful for protocols which demand ascii characters representing hex strings. But if you're just trying to send hex stay away from this function.
  
  send_string dvvidswitch,"$01,($80+input),($80+output),$81" // I think this is what you're trying to do?
