Serial Line IP (SLIP) is used for point-to-point serial connections running TCP/IP.
SLIP is commonly used on dedicated serial links and sometimes for dialup purposes, and is usually used with line speeds between 1200bps and 19.2Kbps.
SLIP is merely a packet framing protocol: SLIP defines a sequence of characters that frame IP packets on a serial line.

  Serial Line Internet Protocol - Wikipedia, the free encyclopedia
The Serial Line Internet Protocol (SLIP) is a mostly obsolete encapsulation of the Internet Protocol designed to work over serial ports and modem connections.
On microcontrollers, however, SLIP is still the preferred way of encapsulating IP packets due to its very small overhead.
Both SLIP and PLIP have been replaced by increasingly-common networks, including home networking – and by other peer-to-peer connections such as USB, used to transfer files to a second computer where a network is not necessary or available.

 Serial Line IP
Packet protocols like IP or IPX rely upon the receiver host knowing where the start and end of each packet are in the data stream.
The comparatively low cost of low-speed dialup modems and telephone circuits has made the serial line IP protocols immensely popular, especially for providing connectivity to end users of the Internet.
All that is required is a modem and a serial port equipped with a FIFO buffer.

 TCP/IP Networking on OpenVMS Systems
IP attaches a header to the datagram that includes the source address and the destination address, both of which are unique internet addresses.
IP routing involves using the destination IP address of a datagram to decide where to send the datagram.
IP routing passes to the network interface software the IP address of the next machine to which the datagram should be routed.

 [Chapter 6] 6.2 TCP/IP Over a Serial Line
A serial interface is just an interface that sends the data as a series of bits over a single wire, as opposed to a parallel interface that sends the data bits in parallel over several wires simultaneously.
This description of a serial interface would fit almost any communications interface (including Ethernet itself), but the term is usually applied to an interface that connects to a telephone circuit via a modem or similar device.
SLIP sends the datagram across the serial line as a series of bytes, and it uses special characters to mark when a series of bytes should be grouped together as a datagram.

 Linux Network Administrator's Guide, 2nd Edition: Chapter 7: Serial Line IP
This speed requires, however, that the serial line be converted to the SLIP mode explicitly.
This is not a real line discipline; instead, it causes the kernel to attempt to identify the line discipline being used by the remote machine and to match it.
These commands are used to flip the serial line to SLIP mode and configure the interface.

 The TCP/IP Guide - Serial Line Internet Protocol (SLIP)
An IP datagram is passed down to SLIP, which breaks it into bytes and sends them one at a time over the link.
If no noise occurred on the line between datagrams then the recipient will just see the END at the start of datagram #2 right after the one at the end of #1, and will ignore the “null datagram” between the two.
IP datagrams are passed down to the SLIP software at layer two (a simplified one with only five bytes is shown here).

The purpose of SLIP is to transmit IP datagrams across a modem line.
SLIP has survived beyond its years, and although it was an innovation in its time, in the context of today's technology a list of SLIP's characteristics looks similar to a list of its shortcomings.
Successive TCP and IP headers often contain redundant information, and there are several strategies for compressing header information.

The serial port is usually connected to an integrated circuit called a UART which handles the conversion between serial and parallel data.
In the days before bit-mapped displays, and today on multi-user systems, the serial port was used to connect one or more terminals (teletypewriters or VDUs), printers, modems and other serial peripherals.
Two computers connected together via their serial ports, possibly via modems, can communicate using a protocol such as UUCP or CU or SLIP.

 Serial Line IP (SLIP)   (Site not responding. Last check: 2007-10-30)
Error detection is not absolutely necessary at the SLIP level because any IP application should detect damaged packets (IP header and UDP and TCP checksums should suffice), although some common applications like NFS usually ignore the checksum and depend on he network media to detect damaged packets.
because dial-in lines are so slow (usually 2400bps), packet compression would cause large improvements in packet throughput.
Usually, streams of packets in a single TCP connection have few changed fields in the IP and TCP headers, so a simple compression algorithms might just send the changed parts of the headers instead of the complete headers.

IP is not a reliable communications facility because it does not require acknowledgments from the sending host, the receiving host, or intermediate hosts.
Unlike IP Broadcasting, IP Multicasting allows packets to be taken off the network only by those clients who have configured their systems to receive the packets.
At the IP level, the MTU is 4092 bytes at a maximum of 4 MB per second and 8188 bytes at a maximum of 16 MB per second.
