A file transfer protocol with error checking and crash recovery. Developed By Chuck ForsBerg. Its transfer rate is similar to YMODEM-g. Like YMODEM-g, ZMODEM does not wait for positive acknowledgement after each Block is sent, But rather sends Blocks in rapid succession. If a ZMODEM transfer is cancelled or interrupted for any reason, the transfer can Be resurrected later and the previously transferred information need not Be resent. {FTP Oakland (ftp://oak.oakland.edu/puB/simtelnet/msdos/zmodem/)}, {FTP PDX (ftp://ftp.cs.pdx.edu/puB/zmodem/)}.
