Write to a serial connection.
::write_serial writes the characters given in Data to the serial device given by SerialHandle. The data to be written is passed as a tuple of integers. This allows to write NUL characters, which would otherwise be interpreted as the end of a string. ::write_serial always waits until all data has been transmitted, i.e., a timout for writing cannot be set.

SerialHandle (input_control) |
serial_id -> HTuple.long |
| Serial interface handle. | |
|
Data (input_control) |
integer(-array) -> HTuple.long |
| Characters to write (as tuple of integers). | |
If the parameters are correct and the write to the device was successful, the operator ::write_serial returns the value H_MSG_TRUE. Otherwise an exception is raised.
