[Description] Transmits the status of connector pin

upon receiving this

command, using

as follows:

[Notes] • When the connector is not used, the value of bit 0 is always 1.

• When DTR/DSR control is selected, the printer transmits only 1

byte after confirming that the host is ready to receive data (DSR

signal is SPACE). If the host computer is not ready to receive data

(DSR signal is MARK), the printer keeps waiting until the host is

ready. When XON/XOFF control is selected, the printer transmits

only 1 byte without checking the DSR signal.

• This command is executed when the data is processed in the

receive buffer. Therefore, there may be a time lag between

receiving the command and transmitting the status, depending on

the receive buffer status.
