[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. |
