========================== - Quick transfers with a minimum of errors - Rescuing lost files - Copyright and other legal matters - Unwritten laws about personal conduct - Privacy - Fax services weigh less than your printer - File transfers through the Internet Speed and safety ---------------- Read about MNP, CCITT V.42, and V.42bis in appendix 2. These are popular methods for automatic error correction and compression of data. Compression gives faster transfers of data. To use them, your modem must have these features built-in. They must also be enabled in the modem of the service that you are calling. Compression is particularly helpful when sending or receiving text, for example news stories and messages in conferences. They ensure faster transfers. They are not of much help when transferring precompressed texts and programs. They may even make file transfers with protocols like ZMODEM, Kermit, and XMODEM impossible. If this happens, temporarily turn off the MNP and V.24/V42bis settings in your modem (more about this in appendix 2). Some online services let users retrieve conference messages using a special get or grab function. This function often comes in two versions: * Grab to display: New messages and conference items are received in an uninterrupted stream without stops between items. Retrieval of text can happen at maximum speed. * Grab to compressed file: New messages and conference items are selected, automatically compressed and stored in a file. This file is then transferred using ZMODEM or similar protocols. Some services offer unattended online work with a variation of the "get compressed file" method. Read about 'offline readers' in
