I think the best solution for supporting alternate devices is to pass the
DOS name to the program, and then let it look up the specifics on that
name if it need Exec level access.  Obviously you can't run a 9600 or 
faster serial port very nicely just by opening "SER2:" or something like
that, but you can certainly pass the DOS name and let the program find
out that SER2: is actually attached to "serial1.device", unit 0, or 
"serial.device", unit 1, or whatever.  The DOS namespace is a level of
complete abstration, while the Exec device namespace isn't, so this feature
should and can be exploited without any disadvantages.
