Explanation

 

 

 

PACING

DTR/DSR*,

Pacing (or handshaking) allows the printer to tell the computer when to

 

XON/XOFF

send information. Select DTR/DSR if your computer requires hardware

 

 

flow control (most personal computers do). Select XON/XOFF if your

 

 

computer requires software flow control (for example, if you are using a

 

 

UNIX workstation).

 

 

 

BAUD RATE

9600*

The baud rate tells the printer how fast information will be transferred

 

300 to 57600

from the computer to the printer.

 

 

 

ROBUST XON

ON*

Appears only when PACING is set to XON/XOFF. If it is set to ON, the printer

 

OFF

sends an XON when the printer is on line and when sufficient buffer

 

 

space has become available. If it is set to OFF, the printer sends one

 

 

XON when it can accept more data or when it is on line.

 

 

 

DTR POLARITY

HI*

Determines whether pin #8 is high or low when the printer is ready. When

 

LO

it is set to HI, pin #8 is high when the printer is ready. When it is set to LO,

 

 

pin #8 is low when the printer is ready.

 

 

 

*Indicates factory default.
