Definitions for "Ymodem"
Keywords:  xmodem, zmodem, noisy, batch, faster
Protocol which transfers more than one file at a time. It can use both 1024 byte blocks and 128 byte blocks.
Another common modem file transfer protocol. : The filename extension used by files compressed with the Unix Compress program. : A filename extension used by files compressed with the Unix gzip program.
protocol for transferring files during direct dial-up communications. It is so named because it builds on the earlier Xmodem protocol. Ymodem sends data in 1,024-byte blocks and is consequently faster than Xmodem; however, it doesn't work well on noisy phone lines. Ymodem has undergone a few enhancements: Ymodem-Batch can send several files in one session, and Ymodem-G drops software error-correction, which speeds up the process by removing the overhead used by error-correction. This works because all modems since the V.32 era have error-correction built into the hardware.
