XModem
One of the most popular file transfer protocols (FTPs). Xmodem is fairly effective at detecting errors. It
sends blocks of data together with a checksum and then waits for acknowledgment of the block's receipt.
The waiting slows down the rate of data transmission considerably, but it ensures accurate transmission.
Xmodem can be implemented either in software or in hardware. Many modems, and almost all
communications software packages, support Xmodem. However, it is useful only at relatively slow data
transmission speeds (less than 4,800 bps). Enhanced versions of Xmodem that work at higher transmission
speeds are known as Ymodem and Zmodem.
