dbj,

   I will try to break this to you gently.  Your present TX1.SXB code is not well written.  (I understand SX/B may be new to you.  Many of us have made similar mistakes while we were learning.)

Here are some of the problems.

[LIST]*1.) The program as written will make only one check of the alarm trigger before ending.  To check continuously add something like "GOTO Main" at the end of your program.

*2.) The PUSLEOUT command is expecting a Duration value not a quoted string.  In my opinion the compiler should report an error in this case.  Replace your "OT9600" entry with a number representing how many 10ms durations you want the pulse to last.

*3.) The SEROUT command expects to send a single byte serially.  You are attempting to use it to try to send an entire string.  This is a common misunderstanding of how the command works under SX/B.  Again, I think the SX/B compiler should generate an error under this condition but it does not seem to do so at this time.

   To send an entire string check out the LCD_OUT subroutine of the RFID Reader Interface example in the SX/B Help file.  It demonstrates the passing of string data to a subroutine, which in turn uses the SEROUT command to send the data serially one byte at a time.

*4.) While technically not a problem, the ELSE statement and the NOP command are not necessary and can be omitted.[/LIST]
   Other than that, you appear to be on the right track.  Let us know how it goes.
