Enable Telephony Controls in Control Panel for a Unimodem
If you are using a telephony based modem (unimodem) you can enable the telephony controls in the Control Panel by renaming TELEPHON.CP$ to TELEPHON.CPL in the \Windows\System directory. This will allow you to do diagnostics as well as configure your modem.
1.Right Click on My Computer
2.Select Properties
3.Select the Device Manager tab
4.Select Computer and click Properties
This will show which IRQs are currently in use.
Note: You can also see the I/O, DMA and Memory usage by your hardware.
In Windows 95, your modem may seem to work fine, but the baud rate for your COM Port sometimes doesn't allow you to reach top-speed. To improve your port's speed:
1. Click Start, Select Settings > Control Panel, open System
2. Click the Device Manager tab, and click on the "+" sign next to
Ports (COM & LPT)
3. Select the port your modem uses, click Properties, then click the
Port Settings tab, and set the Bits per second to 115200 bps, that way
you won't have a sort of filter on the Port.
115200 bps is the maximum setting for a "Standard" COM port. If you encounter problems, try setting this value lower. With System Monitor you can check if there are any problems. System Monitor (sysmon.exe) can be found on the CD-ROM version of Windows 95, or can be downloaded from Microsoft (56Kb)
(If you are not sure which COM port your modem uses, click on the "+" sign next to the Modem Icon in Control Panel and select your Modem. Click on Properties and choose the Modem Tab. Here you will see the COM port used by your modem)
4.For most modems you should use Hardware in the Flow control drop-down box.
For for more information, visit the Navas Group Web Site at http://home.att.net/~modemfaq/maxmtu.htm
or http://ModemFAQ.home.att.net/index.htm.
Here you'll find info on the MaxMTU fix, and other settings to increase
your comm's speed. John Navas has had one of the best web sites for
modem information for several years. I have used his web site for
information
If you need to check your IP address, or force Windows to contact the DHCP server again (if the DHCP scheme has changed, or you are having network connecivity problems) tun the program Winipcfg.
1. Click the Start button
2. Select Run
3. Type winipcfg and click the Ok button
4. If Winipcfg does not run and returns an error message, you
probably have a problem with your network configuration.
I recommend that you remove and reinistall TCP/IP components. This may involve removing and reinstalling all network components if TCP/Ip is the only protocol you use. Microsoft has an article titled "Fatal Error" Error Message Occurs When You Run WINIPCFG at http://support.microsoft.com/directory/article.asp?ID=KB;EN-US;Q286748 and another article titled Error Messages When Running TCP/IP-Based Utilities or Programs at http://support.microsoft.com/support/kb/articles/Q191/0/64.ASP
When Windows 95 doesn't recognize your modem, don't use "Standard 14400
bps modem" or "Standard 28800 bps modem".
This does not enable hardware data compression and correction, which
means that your modem is not working at full speed.
Choose any other modem in the list that is compatible with your modem
(see the manual of your modem), or select a Hayes modem that has about
the same specifications.
Some plug and play modems use a virtual com port. You can verify that your modem uses a virtual com port by opening the Control Panel and selecting the Modem applet. If you install a standard modem, and the com port that your modem uses is not available, your modem uses a virtual com port.
Believe it or not, the only article I have found at Microsoft's web site that discusses this situation involves starting a multiplayer game of Golf. The Article titled Golf: Unable to Select COM Port in Multiplayer Game is at the URL: http://support.microsoft.com/support/kb/articles/Q166/9/43.ASP
Discover Internet
bottlenecks and routes
Windows 95 includes some network utilities called trace route (Tracert.exe)
and ping (ping.exe). You can use these utilities as a preliminary
to test a connection to a server. Please note that if the owner of
the server has a firewall, they may disable the ability to respond to ping
and trace route requests.
Another good test to see if a site is available is to go to http://www.netcraft.com and choose "What's that site running?". Netcraft will check the site and return information about the OS and web server that the server it connects to is running. This may be different each time you check a specific site, if they have multiple machines in use that are running different operating systems and web servers.
To use these utilities type the following commands:
ping [server] or specifically ping www.neogeek.net or for an example of a site that blocks the response, ping www.microsoft.com
tracert [server] or specifically tracert www.microsoft.com or for an example of a site that blocks the response, tracert www.microsoft.com
Using tracert, you should be able to get to Microsoft's gateways, before the servers stop responding.
I used an online tracerotue tool located at http://www.infosyssec.com/infosyssec/ipsectools.htm.

Automatic Re-dialing You can configure
Windows 95 to automatically re-dial your Dial-Up connection:
1. Click Start > Programs > Accessories > Dial-Up Networking
2. Select your connection
3. From the menu select Connections > Settings
4. Check Re-dial and select the number of times to re-dial (2-100)
and click OK
5. Close Dial-Up Networking
If you have a dial-up connection configured to automatically redial
your Internet service provider (ISP), you may receive the following error
message after the fifteenth automatic redial attempt:
Could not detect modem. It may be in use, turned off, or not installed properlyFor a solution, see Microsoft Knowledge Base Article Q258838
Do you frequently
get disconnected?
If you get disconnected frequently, try this extra modem setting:
1. Go to Modems in Control Panel (Start > Settings
> Control Panel)
2. From Modems select Properties, select the Connection
Tab, select Advanced
3. In the Extra settings dialogue box, enter S10=50
This will force the modem to stay connected without a carrier, up to 5 seconds.
