* (n = 0)
Sends the current status of pin No. 3 of the drawer kick connector.
•n is as follows.
n = 0: Drawer kick connector pin No. 3.
•The status sent is 1 byte. The contents are as shown in the following table.
•If nothing is connected to the connector, bit 0 of n is always "1."
•In the case of DTR/DSR control, after confirming that the host is ready to receive (the DSR signal is High), one byte only is sent. In the case of XON/XOFF control, one byte only is sent without confirming the status of the DSR signal.
•In the case of DTR/DSR control, if the host is not ready to receive (the DSR signal is Low), it waits until the host is ready to receive.
