XON/XOFF

 

DTR/DSR is a hardware handshaking setting.

 

XON/XOFF/DTR

This menu item applies only to the serial port if Serial Protocol is set to

 

 

XON/XOFF.

 

 

 

 

Baud

Specifies the rate at which data can be received through the serial port

 

9600

Notes:

 

19200

 

9600 is the factory default setting.

 

38400

 

138200, 172800, 230400, and 345600 baud rates are only displayed in the

DSR is a handshaking signal used by most serial cables. The serial port uses

 

 

DSR to distinguish data sent by the computer from data created by electrical

 

 

noise in the serial cable. The electrical noise can cause stray characters to

 

 

print. Set this to On to prevent stray characters from printing.
