Handshake
Handshaking in the serial environment is most commonly handled by
software and/or hardware. The manipulation of the hardware hand-
shaking is handled by the following 4 lines:
`
RTS (Request to Send)
`
CTS (Clear to Send)
`
DSR (Data Set Ready)
`
DTR (Data Terminal Ready)
Ready/Busy (Hardware Handshake)
When Ready/Busy protocol is selected, DTR will be used to pace the
data flow from PC. When the serial interface is BUSY (Buffer is full,
Printer is out of paper or an error is detected), DTR will be dropped to
indicate to PC that Printer cannot receive any more data.
XON/XOFF (Software Handshake)
When XON/XOFF protocol is selected, Printer indicates to PC that it
is busy and not ready to receive any more data by sending an XOFF
(DC3 X’13’) character. When the serial interface is ready to receive
more data, an XON (DC1 X’11’) will be transmitted.
