I'm trying to control access to a videodisc player (Pioneer 6000) from
within a relational database application, written in 4th Dimension for
the Mac.  Before I set out to do it myself, has anybody out there either
1) written the 4D external interface routines already (in C preferably),
2) adapted the existing Hypercard XCMD (written in Pascal, I believe) to
work under 4D, or 3) written the interface routines within 4D, using the
serial port communications primitives?

Code, comments, and suggestions are much appreciated.
Thanks,
