Hi folks,

You may or may not be able to help me with this, but I would GREATLY
appreciate any insights..

We are trying to use MacTCP (from APDA) on a MacII.  We are having
problems, and APDA is not being particularly helpful.

When trying to access the MacTCP device using the device driver call
PBOpen, we are getting an error #-23 "requested read/write permission
doesn't match driver's open permission" (according to Inside Macintosh).
We are setting the permission parameter ioPermssn (byte 27 of the parameter
block) to the constant 3 (read/write), though we have tried fsCurPerm
(0), fsRdPerm (1) and none of those work either.

If anyone has seen this before, installed MacTCP successfully etc, I
would much appreciate hearing from you.  My email is damon@cs.stanford.edu
(probably better than posting replies here)..

Thanks,
Damon
