Commands 5-33
[Description] Transmits the status of connector pin n, using n as follows:
[Notes] • 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.
• When Auto Status Back (ASB) is enabled using GS a, the status
transmitted by ESC u and the ASB status must be differentiated.
• When the connector is not used, the value of bit 0 is always 1.
• The status to be transmitted is shown in the table below.
