Xon/Xoff Flow Control

Host systems that use a simple three-wire RS232 connection (TXD, RXD, GND) accomplish flow control by using Xon/Xoff or Robust Xon/Xoff. The printer supports these modes and may be selected from the Operator Panel.

When using a three-wire RS232 connection, the printer must still detect the DSR signal as ON. This requirement is addressed by adding a jumper between RTS (pin 5) and DSR (pin 20) on the DB25 male connector on the printer (Figure 9).
