I am using the CTB for AppleTalk ADSP communications, and
am having difficulty with the ADSP connection ritual.

On the server side, I am doing something like:

{
	CMNew()
	CMListen(ASYNC);
	while (NOT accepted)
	{
		CMStatus()
		if (statusListenPend == FALSE && statusIncomingCallPresent == FALSE)
		{
			printf("ERROR listener closed unexpectedly.");
		}
		else if (statusIncomingCallPresent == TRUE)
		{
			CMAccept();
			accepted = TRUE;
		}
	}
	Communicate..... (Calls to CMRead(), CMWrite(), CMConfig(), etc...).
}

Excusing the hideous psuedo-code....

Does this look right? Do I need A CMOpen() in there?
How do the status flags work here? Is my check valid?
Right now, my first attempts at communication lock the
server and the client. This appears to be virtually
undocumented.
