acnet_send_wait

	status.i4.v = acnet_send_wait(dest_node.i2.v, dest_task.i4.v,
				      request_buffer.g.v, request_length.i4.v,
				      reply_buffer.g.v, reply_length.i4.v,
				      timeout.i4.v [,return_length.i4.r])

	This routine sends an ACNET request and waits for a reply or a timeout.

	dest_node	target trunk and node
			(constants are in nodedefs)
	dest_task	target process (radix 50 format)
	request_buffer	request buffer
	request_length	request buffer word length
	reply_buffer	reply buffer
	reply_length	reply buffer word length
	timeout		number of 15 Hz ticks to wait for reply,
                       0 is forever
	[return_length]	number of words returned

	This function returns ACNET status values as follows:

	OK			success
	CBS_GENERR		failed in allocating event flag
	ACNET_UTIME		reply timed out
	ACNET_xxx		request failed

	This function will call error_display if error_imbedded_on has
	been called.

	This function requires the following include files:

	cbslib_h, nodedefs_h, acnet_errors_h

	Related functions:

	acnet_connect, acnet_default_connect, acnet_default_connect_name,
	acnet_chgpgm, ntv_send_request, ntsreq

	C/C++ usage:

	char	request_buffer[REQUEST_LENGTH];
	char	reply_buffer[REPLY_LENGTH];
	short	dest_node = OPER;
	int	status;
	int	dest_task = rad50("SA1082");
	int	request_length = REQUEST_LENGTH / sizeof(short);
	int	reply_length = REPLY_LENGTH / sizeof(short);
	int	timeout = 5 * IPERRT;
	int	return_length;

	status = acnet_send_wait(dest_node,dest_task,
				 (void *) request_buffer,request_length,
				 (void *) reply_buffer,reply_length,timeout,
				 &return_length);
