[slinkelist] Possible slink-x enhancement?

[Richard]

I have at the moment 2 application that use the paralell port on the slinke,

what I do at the moment is read the port, toggle the bit I want to change
and then output it to the port, however if both applications do this at
once, one of the outputs doesnt happen (Only happens under high load on the
system)

Would it be possible to have an application request access to a particular
IO pin(s), and then its calls will _only_ effect that pin(s), with the
request being denied if its already been given to another application.

This would also solve the problem of having to rewrite the aplications
whenever the use for a partucular pin changed.
