. This is almost never aproblem on ISDN, DSL, or cable modems. But on a regular analog telephone line,this can have a major impact. One rather crude method of testing for linenoise is to pick up the telephone receiver (while not connected by your modemon the line) and listen for static-like, crackling sounds. These are oftenindications of line noise. It can be caused by faulty wiring, moisture, andseveral other factors. The best way of getting rid of it is to use as short ofphone cords as possible with your modem, and if problems still persist, callyour telephone provider and have a technician come to your home and analyzeyour line quality. Don't let them leave until it is *crystal* clear to thepoint where you can hear a pin drop.CptSiskoX@Geocities.com========================Data Compression BluesIf you are experiencing random dropped connections, try turning off datacompression. Also making sure that error correction is on and flow control isset for Hardware (RTS/CTS) usually helps. Data compression set "on" is adefault configuration in most modems. When Win95/98 detects a modem, it triesto load an initialization (.inf) file for that modem brand and model. IfWin95/98 isn't sure what modem is installed, it loads a default file namedmodem.inf. With modem.inf being used, Windows may or may not send the correctcommand to disable data compression. If this happens, read your modemdocumentation and enter the AT command to disable data compression. ClickStart, Settings, Modems, Properties, Connection, Advanced, and then type theAT command(s) in the Extra Settings box.Modems have limited buffer space for both error correction and datacompression. Error correction is necessary to provide an error-freeconnection. Also, when errors do happen, modem buffer space is needed tocorrect them. Modems have error thresholds that, when exceeded, will causeserial overruns and will hang up the call, resulting in a disconnection.CptSiskoX@Geocities.com=======...
