Software handshaking uses the XON/XOFF scheme in which an ASCII DC3 (0x13) character is transmitted 

by the receiver to indicate that data transmission should be halted (XOFF), and an ASCII DC1 (0x11) character is 
transmitted to indicate that data transmission may continue (XON). Hardware handshaking utilizes the RTS and CTS 
lines. When the RTS output signal is asserted true, the unit is ready for data. This signal should be connected to the 
external computer's  CTS input signal, so that when the receiver is ready, the transmitter may send data. When the 
unit is not ready for data, it unasserts the RTS signal, halting data transmission. Likewise, the unit monitors the CTS 
input signal during data transmission, halting transmission if the external computer unasserts it's RTS signal.  In 
addition, the 8210A-2-5 unasserts the RTS signal while command execution is in progress. 
 
For those systems incorporating local front panel controls, the serial port can lockout local users, providing a Remote/ 
Local function similar to that of GPIB operation.
