SeaMaxLinGetCommHandle() HANDLE SeaMaxLinGetCommHandle ( SeaMaxLin *  SeaMaxPointer ) Get the handle to the actual communication medium. For RTU types it will be a normal file pointer, but TCP will be a socket handle. For this reason, it was decided to only return RTU file pointers. An attempt to get the socket handle will return an ENODEV error. Parameters [in] *SeaMaxPointer Pointer to a previously opened seaMaxModule Returns int Error code. Return values >0 Pointer to communications termios struct. -EBADF No open module. -ENODEV This is not an RTU type connection. References MODBUS_RTU. Referenced by CSeaMaxLin::getCommHandle().
