A very common form of file transmission, which can be used across dialup and telnet connections. It can be used in batch modes (for multiple files), and it is faster than the older xmodem and ymodem. [..]

An asynchronous file transfer protocol that is more efficient than Xmodem. It sends file name, date and size first, and responds well to changing line conditions due to its variable length blocks. It [..]

WebGuest Dictionary Error control software protocol used to transfer files between modems . Based on Xmodem and Ymodem protocols (but faster!).Sends data in blocks of 1,024 bytes . Zmodem has the ability to recover from a partially transfer.

An asynchronous communications protocol that provides faster data transfer rates and better error detection than Xmodem. In particular, Zmodem supports larger block sizes and enables the transfer to r [..]

A file transfer protocol that includes crash recovery and auto-download features, and can use a 32 bit CRC, which makes it near error-free.

Chuck Forsberg’s fast file transfer protocol. It is designed to work well on packet nets, were it takes considerable time for data packets to wend their way from end to end. If the phone connection is [..]

A file transfer protocol which transmits data between modems in blocks of 512 bytes. It is fast because it does not wait for positive acknowledgement (ACK) after each block of data, but will resend a [..]

ZMODEM is an asynchronous communication protocol that provides faster data transfer rates and error detection than Xmodem. ZMODEM supports enormous block sizes and, following a communication failure, [..]
