HyperTerminal supports the following file transfer protocols.
Protocol | Description |
Xmodem | The most common error-correcting data communications protocol. Most communications packages support (and some only support) Xmodem. This protocol is also supported by most online services. Xmodem is slower than other protocols (for example, Zmodem). |
1K Xmodem | A variant of traditional Xmodem, which sends data in 1K (1024-byte) blocks instead of 128-byte blocks. On some bulletin boards, this protocol is called Ymodem. |
Ymodem | A faster version of Xmodem, transferring data in 1K blocks. |
Ymodem-G | A variant of Ymodem designed for use with modems that support hardware error control. If you cannot transfer files by using Ymodem-G, your modem might not support error control. Use Ymodem instead. |
Zmodem | The fastest data transfer protocol, and the primary choice of most bulletin board users. Zmodem dynamically changes its block size based on line conditions, and it is extremely reliable. |
Kermit | An extremely flexible protocol, found most often on DEC™ VAX™ computers, IBM® mainframes, and other minicomputers. However, Kermit is quite slow and should not be used if faster options are available on the other computer. |
Note You can choose a file transfer protocol to use when you send or receive a file by using the Send or Receive File options in the Transfer menu, as described in online Help.
