A common form of file transmission for dialup and telnet connections, which uses 1K blocks of data. It has two forms–single file mode and batch mode. The single file form is sometimes called 1K xmodem, and the batch mode is sometimes called ymodem batch. Usage is not consistent. Zmodem is newer and more reliable.
