SLIP
SLIP establishes a dial-up connection between two computers over which TCP/IP can flow. SLIP is a trivial protocol (RFC 1055). SLIP simply transmits IP packets and terminates the transmission with a 0xC0 byte. If a byte of 0xC0 occurs in the packet, it is substituted with a {0xDB,0xDC} sequence. If a byte of 0xDB occurs in the stream, it is substituted with a {0xDB,0xDD} sequence. That is the protocol. SLIP requires a serial port configured to transmit 8 data bits, no parity, with either hardware or XON/XOFF flow control. At higher transmission speeds, it is vital to choose hardware flow control.
SLIP is an obsolescent protocol because a SLIP frame does not include error checking. It relies on protocols at higher layers to provide error ...
