The device ID is not available to our programs at run time; you'll have to create a duplicate z-string in a DATA statement for use in TX_OUT as above (by the way, that's an outdated subroutine -- see below).

The ID is included in the assembled code and can be read by using the IDE's Run\Device menu.  This allows us to create a hex file of a program (to protect the source from others) and still have it be identified (once the hex file is loaded into the that dialog).

To keep things trimmer and less complicated I use TX_BYTE and TX_STR in my programs; here are the latest:

[code]' Use: TX_BYTE byteVal 
' -- transmit "byteVal" at "BaudMode" on pin "TX"

SUB TX_BYTE
  tmpB1 = __PARAM1                              ' get byte to send
  SEROUT TX, BaudMode, tmpB1
  ENDSUB

' -------------------------------------------------------------------------

' Use: TX_STR [string | label]
' -- "string" is an embedded string constant
' -- "label" is DATA statement label for stored z-String

SUB TX_STR
  tmpW1 = __WPARAM12                            ' get address of string
  DO
    READINC tmpW1, tmpB1                        ' read a character
    IF tmpB1 = 0 THEN EXIT                      ' if 0, string complete
    TX_BYTE tmpB1                               ' send character
  LOOP
  ENDSUB [/code]
