Create control block, with input and output buffers, a base socket with host and port assigned.
If srvFlg is TRUE, bind a name to the socket and listen.

tsRcv( int handle, char* rcvDat, char* match, int maxRx, int to )
|
Receive characters until either the character count reaches "maxRx" or the "match" pattern is found in the received data or the time out "to" expires.
Returns bytes received or an error (negative of errno) or zero if timed out.

If the socket is not yet connected, it will be connected to the previously indicated host and port (tsOpen()).
Returns bytes transmitted or an error (negative of errno) or zero if timed out.
