Debug and LCD

Hello Stampers,
Just a taught......
I frequently use the BPP-420 4x20 Serial LCD module (Scott Edwards) in
combination with the basic stamps.
Wat I want to do is to use an LCD module as a debug output screen, connected
on the dedicated "program-debug" port 16 .
I 'll to put several debug statements in the program, and if the LCD module
is connected it must display the debug output strings, when the LCD isn't
connected, the program simpy runs blind.
I think this will be helpfull for "in the field" problem solving.
Has anybody already done this, or can sombody give me a few hints..........
Thanks in Advance
Met vriendelijke groetjes,

You shouldn't use the 'DEBUG' statement, though,
as it is NOT included in code compiled for 'running'.
You should use:
SEROUT 16, 16384 + 84, "Debug Statement", 13
This does exactly what a DEBUG statement does,
except it is included in running code.
Oh, and the '16' above indicates to use the
'programming port'. You can actually use ANY
I/O pin 0 through 15. If you get a 'serial
back-pack' for your LCD, you are good to go.
If you MUST use the physical pin 1 and 2 on
the module (the programming port) you should
be aware that these pins implement a pseudo
max232 circuit, which modulates the -12 volts from
the PC TX line to make a good RX-Out signal.
You may have to do something to get this to
work -- like connecting -12 to the TX pin.
Now all you need is a

SEROUT with slightly different formatting (and devoted to pin 16 at 9600
baud). I routinely create programs that use DEBUG and ultimately end up
communicating with a generic terminal program. With PBASIC 2.5 you can
also use DEBUGIN (a simplified version of SERIN on pin 16 at 9600 baud)
to get information from a terminal.
