[Caution] | This command is valid only for the serial interface. If nothing is connected to the connector, |
| the bit 0 will be always "1". In case of DTR/DSR control, if the host cannot receive (DSR |
| signal has the Mark status), the printer will wait until it will be ready to receive. In case of |
| XON/XOFF control, only one byte will be sent without confirming the status of the DSR |
| signal. Note that it may take time to send the status after receiving the command. |
