acnet_wait

	status.i4.v = acnet_wait(task.i1a.r, timeout.u2.v)

	This routine waits until the next ACNET message (request or reply)
	is received for the requested task or the requested timeout elapses.

	task		ASCII task name (PROCESS_NAME_LEN characters)
			(name used in acnet_connect call)
	timeout		timeout in milliseconds (If a value of zero is passed,
			this routine will return immediately.)

      	This function returns status values as follows:

	ACNET_NO_MESSAGE	no message received
	ACNET_REQUEST_RECEIVED	ACNET request received
	ACNET_REPLY_RECEIVED	ACNET reply received

	cnsparam_h, acnet_h, acnet_errors_h
