Original BS2 to TI83Plus can send data to a RS232 connected device

Hello!
Okay I've just managed to confirm that the normally debug displayed output which can be sent to the serial configured displays that the firm sells will also work to serial connected other devices.
Consider:

' {$STAMP BS2}
' {$PBASIC 2.0}

serdata   VAR   Byte

again:
'
'*****this will wait for serial from calculator
SERIN 15,396,[serdata]
SEROUT 14,396, [DEC serdata, CR]
'***this will send it to the pc debug screen
'DEBUG DEC serdata, CR

'***this will send the same data plus 1 back to the calculator
serdata=serdata + 1
SEROUT 15,396,[serdata]
'DEBUG DEC serdata, CR
SEROUT 14,396, [DEC serdata, CR]

GOTO again

The code above is setup to send from Pin 14 out to a (too long discontinued) DS275, that device translates the serial stream from the pin into a RS232 level-shifted output. It in turn gets sent into a Palm Pilot running either an app called PalmOrb or one named after a type of fungus. To use that one change the baud to 84. (Which is 9600 baud.)
That line looks like this:

SEROUT 14,84, [DEC serdata, CR]

Oh and if anyone does have the Palm 3 and does want to try this, I can supply both apps. (The PalmOrb one is at https://palmorb.sourceforge.net/ but the one named PortaBella was available from its vendor, which sadly is now closed. Which is why I can privately provide it. )
However no mascots were involved in the creation of this post.
