For a service like FTP, to disconnect would be QUIT/r/n
. If a command string is not specified, the connection is closed by sending a FIN packet and then an RST packet.
The /r
(carriage return) and /n
(line feed) are the conventions for sending these control characters to terminate a string. You can use:
/r = 0x0a
/n = 0x0d
/t = 0x09
or /xnn
where nn
is any hexadecimal value from 00 to FFThe disconnect string is:
Send=QUIT/r/n
