Windows XP much like ever other Windows Operating System offers several improvements over the previous release (Most of modem error 651 broadband the time) & Windows XP is no exception, offering some nice updates to the Networking features. This guide will take you through optimizing the performance, reliability & security of your Dial-up connection in Windows XP as well as several other tips. Internet Connection Setup Click on Start, Control Panel, then Network Connections. Right click on your Internet connection & select Properties. Then select Configure button. Maximum speed (bps). Users of 33.6K Modems should set this to 56700, while 56K Modem users should select 115200. Enable hardware flow control. Tick this setting to enable the use of hardware handshaking with your connection. For best connection stability & throughput ensure this setting is Ticked. Though in some (rare) cases you may find Unticking this setting can improve connection stability (Uses Software flow control instead). Enable modem error control. Tick this setting to enable the use of Modem error control, which will attempt to ensure data integrity in the connection, resending any damaged packets as necessary. I’d highly recommend enabling this. There are also Init strings available which can be used to disabled inefficient error control components. Enable modem compression. Data compression provides faster uploads/downloads depending on the data which is ge

Business Modems go through a link negotiation process with the remote device. Another name modem error 633 for the negotiation process is "handshaking." The Courier 56K Business Modem Attempts to find both the highest compatible modulation and

the highest rate, in the following order: V.92, V.90, V.34, V.32 bis, V.22 bis, V.22 (Bell 212), and Bell 103. Selective Reject The Courier 56K Business Modem supports Selective Reject for analogue calls. Selective http://www.techspot.com/tweaks/winxp_modem/ Reject improves performance on noisy lines by reducing the amount of overhead incurred when the protocol must resend data due to errors. When Selective Reject is active, only the frame that contained the error is re-sent, instead of the frame plus all of the following unacknowledged frames. Selective Reject is an optional part of the ITU-T V.42 (LAPM) standard. For your modem to Command Enable Selective Reject http://support.usr.com/support/3453c/3453c-ug/handshaking.html ATS51.6=0 (Default) Disable Selective Reject ATS51.6=1 Attaining Speeds Above 28.8 Kbps V.34 connections at 21.6, 24, and 26.4 Kbps are common. To get connections of 28.8, 31.2, and 33.6 Kbps, line quality must be pristine end-to-end. Attaining 56K Connections When a client V.92 modem connects to a server V.90 or V.92 modem, the path through the telephone network between the modems is subject to the following conditions for a V.92 connection to be made. A digital connection at one end. ISPs or other online services must have a digital connection to the public switched telephone network (PSTN). Most major online services have a digital connection to the PSTN. Only one digital-to-analogue conversion. There can be only one digital-to-analogue conversion in the telephone network between the V.90 server modem and the V.92 client modem. Controlling the V.8 Call Indicate Tone The V.8 protocol speeds call negotiation and specifies a call indicate tone. Providing the call indicate tone is optional. For compatibility, we ship the Courier 56K Business Modem with the call indicate tone disabled. For your modem to Command Enable the call indicate tone ATS54.6=0 If you enable the V.8 call indicate tone, expect to hear a sound like a fast ringi
09/01/03 8:04pm Windows 95/98/ME/XP FORCED ERROR CORRECTION The single most important modem setting that fixes the vast majority of connection problems is called 'required to connect' in Windows 98/ME and 'Forced Error Correction' in XP. Error correction is necessary to have a solid http://www.lightlink.com/cgi/show.cgi?disc4.script connection, it allows the modem to filter out noise and not take noise as data. By default your modem will try to *NEGOTIATE* for error correction implying that if the line is not good enough it will sign on with out it. This is disasterous and almost ALWAYS results in a disconnect soon after. Most modems negotiate for error correction sucessfully every time, but on marginal lines sometimes they fail, then you get on, but modem error its a bad connection so you get dumped. The answer to this is to *FORCE* the modem to use error control, this bypasses the negotiation phase, and forces the modem to use it whether it wants to or not. If the line is so bad the error control just can't work, the modem will not sign on at all. The end result is that if the modem DOES sign on, you know you have modem error 651 error control working and much less chance of getting booted at the next noise burst. WINDOWS 95/98/ME Goto MY COMPUTER -> DIAL UP NETWORKING, put mouse on lightlink/onlineimage icon, hit with RIGHT button, pull down on PROPERTIES. Hit on CONFIGURE, make sure modem speed is set to 115200, -> CONNECTION across the top, -> ADVANCED lower right. Upper left USE ERROR CONTROL, REQUIRED TO CONNECT, AND COMPRESSED DATA should all be on. It's that REQUIRED TO CONNECT that is often off. Turn it on and make sure it stays on! Upper right USE FLOW CONTROL and HARDWARE should be on. In modem EXTRA SETTINGS put S10=20, this will increase your modems tolerance for momentary breaches in the carrier signal due to noisey phone lines. Hit OK all the way out, *NOT THE X IN THE UPPER CORNER* to make sure your work is saved. Next time you sign on, forced error correction should be in effect. WINDOWS XP Windows XP makes it a bit harder to find the forced error correction setting, so for many this has never been turned on. So it is vitally important that anyone running XP do so as soon as they can. Goto START -> CONTROL PANEL -> PHONE+MODEMS -> MODEMS, highlight the modem you are actualy using if more than one is listed, -> PROPERTIES, -
