4.1 RS-232 PARAMETERS

4.1.1 Handshaking

Hardware handshaking: (RTS/CTS)
The RTS line is activated by the decoder before transmitting a character.

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

RTS/CTS handshaking


Software handshaking: (XON/XOFF)
During transmission, if the Host sends the XOFF character (13 Hex), the decoder

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

when the XON character (11 Hex) is received.
