[comp.lang.pascal] Device Redirection: AUX device with turbo pascal

kleman@magnus.ircc.ohio-state.edu (Gary L Kleman) (12/12/90)

I am having trouble with a AUX device driver originally written in
Turbo Pascal 3.0  (yes, turbo pascal 3).  In tp 3, there were device 
addresses, such as AuxInPtr and AuxOutPtr, which allowed you to modify
 the vectors so they point to different procedures such as RS232_in and
function RS232_out.  You can still access by the AUX device, but it
uses the new functions.

Now my question: I have upgraded to tp 6.0 and cannot find any reference
in the manual for AuxInPtr or AuxOutPtr, and they do not compile (unknown
identifier).  Can someone tell me if the names have been changed or how
to do the same thing in this newer version.

Any help would be appreciated.
