The Serial Line Internet Protocol (SLIP) is an encapsulation of the Internet Protocol designed to work over serial ports and modem connections. It is documented in RFC 1055. On personal computers, SLIP has been largely replaced by the Point-to-Point Protocol (PPP), which is better engineered, has more features and does not require its IP address configuration to be set before it is established. On microcontrollers, however, SLIP is still the preferred way of encapsulating IP packets due to its very small overhead.
SLIP modifies a standard TCP/IP datagram by appending a special "SLIP END" character to it, which distinguishes datagram boundaries in the byte stream. SLIP requires a serial port configuration of 8 data bits, no parity, and either EIA hardware flow control, or CLOCAL mode (3-wire null-modem) UART operation settings.
SLIP does not provide error detection, being reliant on upper layer protocols for this. Therefore SLIP on its own is not satisfactory over an error-prone dial-up connection. It is however still useful for testing operating systems' response capabilities under load (by looking at flood-ping statistics).
SLIP is also currently used in the BlueCore Serial Protocol for communication between Bluetooth modules and host computers.

Famous quotes containing the words serial and/or line:
“An autobiography is an obituary in serial form with the last instalment missing.”
—Quentin Crisp (b. 1908)
“If you’re anxious for to shine in the high esthetic line as a man
of culture rare,
You must get up all the germs of the transcendental terms, and plant
them everywhere.
You must lie upon the daisies and discourse in novel phrases of your
complicated state of mind,
The meaning doesn’t matter if it’s only idle chatter of a
transcendental kind.”
—Sir William Schwenck Gilbert (1836–1911)
