I would try replacing what you have in the "name" attribute for CFEXECUTE
with this:
"/opt/coldfusionmx/wwwroot/DMS/receipts/print_form.pl > /dev/ttyS0"
or
"/opt/coldfusionmx/wwwroot/DMS/receipts/print_form.pl>/dev/ttyS0"
and then leave the "outputfile" attribute empty. CFEXECUTE's outputfile
attribute might not behave in the same way as the command you're issuing
in the command shell.
If that doesn't work another option might be to use the Perl script itself
to talk directly to /dev/ttys0 instead of capturing the output of the
.pl file and writing it to the device.
