PARAMETER ISSUES AND DEFINITIONS 4

Hardware handshaking: (RTS/CTS)

The RTS line is activated by DLCC before transmitting a character. Transmission is

possible only if the CTS line (controlled by the Host) is active.

Hardware RTS/CTS Handshaking

Software handshaking: (XON/XOFF)

During transmission, if the Host sends the XOFF character (13 Hex), the card

interrupts the transmission with a maximum delay of one character and only resumes

when the XON character (11 Hex) is received.
