[comp.sys.mac.comm] Problems with Appletalk under MPW 3

rob@cs.mu.oz.au (Robert Wallen) (02/05/91)

The gist of the problem is as follows.  I have a driver which is opened at 
startup by an INIT; this starts up Appletalk (MPPOpen,ATPLoad,NBPLoad), opens
a general socket (accepts calls from 0,0,0) registers a name using that socket
and starts a non-blocking ATPGetRequest.  Then, at accRun time, I look at the
abResult field to see if it has finished.  It never does.

I have another Mac on the same Localtalk and using one of those peek programs
can see my other device actually trying to talk but the request never gets thru.
I have a previous version which was compiled with MPW 2.x which works fine; the
new version (which admittedly has some other changes but none I can see would
affect me) compiled with MPW 3.x doesnt work.

Was there any change to the appletalk interfaces (I am using the 'old-style')
to fix bugs from MPW 2.x to 3.x?  Is there anything else that might have got
covered in Tech notes that I havent seen?

Reply by mail please, I'll summarize if appropriate.  Thanx in advance...
