Kermit

communications A popular packet-oriented protocol from

Columbia University for transferring text files and

binary files on both full-duplex and half-duplex 8 bit

and 7-bit serial connections in a system- and

medium-independent fashion, and implemented on hundreds of

different computer and operating system platforms. On

full-duplex connections a sliding window protocol with

selective retransmission provides excellent performance and

error recovery characteristics. On 7-bit connections, locking

shifts provide efficient transfer of 8-bit data.

When properly implemented, as in the Columbia University

Kermit Software collection, performance is equal to or better

than other protocols such as ZMODEM, YMODEM, and XMODEM,

especially on poor connections.

Kermit is an open protocol - anybody can base their own

program on it, but some Kermit software and source code is

copyright by Columbia University.
