ZMODEM actually started as a file transfer tool/protocol for UNIX, not DOS (an incremental improvement over YMODEM by Chuck Forsberg) - the program was called 'sz' (for send zmodem) and 'rz' (for receive zmodem) and then later Chuck created DSZ (DOS Send ZMODEM, which does both the send and receive in the same executable). Then FDSZ (FOSSIL DSZ) and GSZ (Graphical SZ for DOS) and other variants (proYamm and what not). RIP Chuck.
