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.
A form of Xmodem that has the capability to run batch file transfers.
This is a protocol for transferring files during direct dial-up communications. It is faster than Xmodem, but does not work well on noisy phone lines. Ymodem-G drops the software error correction, which speeds up the process by leaving hardware-based error correction in modems.
A file transfer protocol, faster than Xmodem, but not as advanced as Zmodem.
A protocol for transferring drawings electronic files.
A faster version of the XModem.
File transfer protocol which uses data blocks of 1 Kbyte and transfers filenames and more than one file in one transfer. See also Xmodem, Zmodem.
Another file transfer protocol, slightly faster than XMODEM.
An error-checking protocol that can send several files of data at a time in 1024-byte (1K) blocks. This protocol can use either checksums or CRC for error checking.
An improved form of the Xmodem protocol with an ability to send multiple files in a single transfer.
Another form of XMODEM protocol that allows the batch transfer of files.
YMODEM is a protocol for file transfer used between modems. YMODEM was developed by Chuck Forsberg as the successor to XMODEM and MODEM7, and was first implemented in his CP/M YAM program. It was formally given the name "YMODEM" in 1985 by Ward Christensen.
