Are K56 flex or X2 modems compatible with RollaNet's modems?

Our modems are V.90 compatible. If your K56Flex or X2 modem is not dual K56Flex and V.90, or dual X2 and V.90, then you will need to get the V.90 upgrade from your modem manufacturer's web site. As well, many V.90 56K modems were manufactured using V.90 before the V.90 standard was even ratified. Many of these modems will also need to be upgraded in order to assure compatibility with the latest V.90 modems. We have provided link to a 56K modem information site that can aid you in finding the right drivers for your modem. The address is http://www.56k.com/links/V90_Upgrades/. You may also want to talk to Helpdesk (364-0852) to check for possible initialization strings to place under the properties of your modem that may help your connections.

One more thing to consider is that there are some "dual" K56Flex and V.90 or X2 and V.90 modems that can use either standard to connect. If you have trouble with low-speed connections or abrupt disconnections, you may need to find an init string from your modem manufacturer that will disable the dual X2 or K56Flex function, so that the modem will only try to connect at V.90.

How do I verify what modem is installed on my Windows9x computer?

To find out what modem(s) may be installed on your computer, click on: Start | Settings| Control Panel, then double-click on Modem. Your modem type will be found there.

What is a modem initialization string and where can I find one for my computer?

Before your modem software dials a phone number, it initializes (inits) the modem by sending it a series (string) of commands, typically Hayes commands. These commands configure the modem's options for things like error correction, data compression, flow control, and many other parameters. The modem manual should list the Hayes commands the modem recognizes, and what effect each command has.
The important thing about modem init strings is that having the right one often makes the difference between connecting and not. Init strings are fairly specific to each modem. The string that made your friend's modem fly may not work at all for your modem.
Not all programs use simple init strings. Some use settings files, such as Windows 95 .inf files, Mac CCL modem scripts, etc.

To add an init string to Windows 95 Dial-Up Networking:

• Double click My Computer, then double click Dial-Up Networking. (If a Dial-Up Networking folder is not present in My Computer, use this method: From the Start button, choose Programs, then Accessories, then Dial-Up Networking.)
  
• Right-click on your connection icon and choose Properties.
  
• Click the Configure button.
  
• Click the Connection tab.
  
• Click the Advanced button.
  
• Enter the init string in the Extra Settings field.
  
• Click OK to save changes.

The commands you enter here add to the existing string in the .inf file. However, if the string you enter contains any &F command, it essentially replaces the existing string, because the &F commands reset the modem to the factory defaults.

The first place to look for an init string for your modem is in the modem manual. Your manual may list a recommended init string. Otherwise, try one of the following sites:

Ask Mr. Modem
Itsnet's PC Modem Init Strings
Jay's Modem Initialization Strings
Juno's Init String Reference
Modem Select-O-String
