- (D)ownload File
-
- Entering 'D' from the menu will allow the caller to download
- (receive) a file. Xmodem (checksum & CRC), Ymodem (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 CHECKSUM. The plainest error-correcting
- protocol, useful for downloading to old computers or
- those running antiquated communications software.
- Blocks are 128 bytes long.
-
- 3 - XMODEM CRC. Xmodem with slightly superior (CRC) error
- checking. Most programs written in the last few years
- can download using this.
-
- 4 - XMODEM-1k CRC. 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. Ymodem allows faster file
- transfer when used under packet switched networks such
- as PC Pursuit.
-
- External File Transfer Protocols:
-
- The SysOp may, at his/her option, enable a number of
- external 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.
