status.i4.v = tcp_send_wait_by_handle(handle.g.v, request.g.v,

	This routine will send a message to the specified host and
	port and will wait for a reply or a timeout.  The program
	should have connected to this host and port by calling

	handle		handle value (from call to tcp_connect_by_handle)
	request		TCP/IP message buffer
	request_length	size of message to be sent 
	reply		returned TCP/IP message buffer
			(must be as large as the value specified
			 for "reply_length")
			(TCP_MAXLEN is maximum message size supported)
	reply_length	maximum number of bytes to be received
	timeout		number of seconds to wait for reply
			(A value of 0 indicates to wait forever.)
	[return_length]	returned size of message actually received in bytes
	[abort_func]	abort callback function which should return a value
			of TRUE if the caller wishes to abort
			(called as: abort_it = abort_func())

	This function returns ACNET status values as follows:

	OK			success
	CBS_INVID		not connected to this host and port
	CBS_GONE		this socket is not longer open
       CBS_TOO_BIG             not all the data was written to the socket
	CBS_REQLIMIT		message clipped to maxlen
	CBS_TIMEOUT		timed out waiting for reply

	This function requires the following include files:

	cbslib_h, acnet_errors_h

	C/C++ usage:

	int	status;

	status = tcp_connect_by_handle(tcp_host,tcp_port,&handle,message_func);
	status = tcp_send_wait_by_handle(handle,(void *) request,request_length,
