Hardware Control Signal Descriptions
For all RS-232 input and output signals, the Z4Mplus and Z6Mplus printers follow both the
Electronics Industries Association (EIA) RS-232 and the Consultative Committee for
International Telegraph and Telephone (CCITT) V.24 standard signal level specifications.

When DTR/DSR handshaking is selected, the Data Terminal Ready (DTR) control signal
output from the printer controls when the host computer may send data. DTR ACTIVE
(positive voltage) permits the host to send data. When the printer places DTR in the
INACTIVE (negative voltage) state, the host must not send data.

Request to send (RTS) is a control signal from the printer that is connected to the clear to send
(CTS) input at the host computer. RTS is always active (positive voltage) when the printer
is on.

When XON/XOFF handshaking is selected, data flow is controlled by the ASCII
Control Codes DC1 (XON) and DC3 (XOFF). The DTR Control lead has no effect.
