- (D)ownload File
-
- Entering 'D' from the menu will allow the caller to download
- (receive) a file. Xmodem (checksum & CRC), Xmodem-1K (CRC),
- and ASCII protocols are supported. The caller may NOT enter
- a directory or drive specifier here, but instead must have
- specified the appropriate path beforehand. The system will
- prompt for the filename, look for the file, and if it finds
- it then prompt for the protocol. The caller will see:
-
- 1 - ASCII. This is for the ASCII protocol. This should ONLY
- be used for text files, not for compiled programs,
- source code, or compressed or archived files (.ARC,
- .ZIP, .LZH, etc.) where error correction is necessary.
-
- 2 - XMODEM. Perhaps the first error-correcting protocol,
- it is available in almost all communications software.
- Because blocks are only 128 bytes long, it should only
- be used at baud rates of 300 or 1200 baud.
-
- 3 - XMODEM-1K. This protocol is used more frequently at
- baud rates of 2400 or higher, or over fairly clean
- telephone lines. As blocks are 1024 bytes long, less
- time is spent error checking.
-
- Other File Transfer Protocols:
-
- The SysOp may, at his or her option, enable a number of
- additional file transfer protocols.
-
- If someone calls in at 7 data bits, even parity, MEGAHOST switches
- to 8 data bits, no parity before file transfer, and after the
- transfer returns to 7 data bits, even parity.
