Change the OpenRFPerm to OpenResolver. For some reason, that solves the
problem. I don't know why.

Here is what to do to the MacTCP header files that are provided:

In MacTCPCommonTypes.h, change the "ifndef/include" definition to look
like this:

#ifndef _MacTypes_
#include <MacTypes.h>
#endif /* _MacTypes_ */

In UDPPB.h, comment out the word "pascal" in the declaration of
UDPNotifyProc so that it looks like this (THINK C doesn't like a
typedefed pascal funtion):

typedef /*pascal*/ void (*UDPNotifyProc) (
		StreamPtr udpStream, 
		unsigned short eventCode, 
		Ptr userDataPtr,
		struct ICMPReport *icmpMsg);

Do the same thing in TCPPB.h for TCPNotifyProc:

typedef /*pascal*/ void (*TCPNotifyProc) (
		StreamPtr tcpStream,
		unsigned short eventCode,
		Ptr userDataPtr,
		unsigned short terminReason,
		struct ICMPReport *icmpMsg);

You will not be able to use these typedefs in your own programs; they
are only to deal with other declarations in your header files. In your
code, declare your notify procs as 'pascal void whatever' with all of
the parameters as they are declare in the typedef.

That's all I have found so far, except that in my copy of TCPPB.h,
instead of the csCode for receive buffer return being TCPBfrReturn as
documented, it was TCPRcvBfrReturn. I changed it to TCPBfrReturn.
