YMODEM A file transfer {protocol} used between {modem}s. YMODEM was developed by Chuck Forsberg as the successor to {XMODEM} and was itself succeeded by {ZMODEM}. XMODEM used 128-byte {packet}s, YMODEM can also use 1 kilobyte packets. Whereas YMODEM is a batch protocol, {YMODEM-G} is a non-stop version. File sizes are included in the YMODEM header when sending both binary and text files. Thus files transferred via YMODEM should preserve their exact length. File modification times may also be present in the YMODEM header. YModem can {fall back} to smaller packets when necessary but there is no backward compatibility with XModem's error detection.

YMODEM-G A non-stop "streaming" version of {YMODEM} designed for "error-free" connections with proper flow control; the transmitting program sends packets to the receiver as fast as it can without waiting for acknowledgements. Any errors cause the entire file transfer to abort. |
