so on. The modem attempts to make the highest connect rate that your telephone line can support at the time of negotiation. If the line conditions (noise, telephone company routing, etc.) won’t allow a high data rate connection, then the modem will automatically connect at the most reliable rate. Try making the call again after a few minutes.

If you are attempting to make a call from an office and you have to dial “9” to reach an outside number, you are using a PBX. The modem cannot connect faster then V.34 if you are using a PBX. If possible, try using the line that is connected to a fax machine. Fax machines are usually not connected through the PBX.

Your phone line may not support a 56K connection or may support a 56K connec- tion only intermittently. Before a 56K connection can be established the telephone company must have you connected to the Public Switched Telephone Network (PSTN) in a particular way. The modem you are calling must also support 56K connections. The phone line must also be free of distortion and noise. Check to see if you have good voice communications over the line, while talking on a telephone normally.

Appendix A: Non Plug-N-Play Installations

In some cases, because of the operating system, type of motherboard, or BIOS you are using, it is advisable to avoid attempting Plug-N-Play installations. Installing the modem without utilizing the Plug-N-Play features (where those features are avail- able) of your computer and its operating system allows you to dictate the COM port and interrupt that are used by the modem.

The 56K ISA Master facilitates installation on user-defined COM ports and IRQs using jumpers on the modem card itself. (See Below.)

COM Ports and Interrupts

The modem will need one IRQ (also known as an interrupt) and one COM Port to function. To check for any available interrupts, right-click the My Computer icon on the desktop and choose Properties. Select the Device Manager tab. Click Properties to view the System Resources. There are 16 interrupts (numbered 0-15) available in a system. Make a note of any interrupt not listed. If you do not have any free inter- rupts you may need to disable an existing device that you are not currently using, such as COM2 on your motherboard. This will free up I/O port 0x2F8 and IRQ 3.

Disabling COM 2 or adjusting the Plug-N-Play settings is done from the BIOS setup, You can normally enter the BIOS setup menu by pressing a key or a combina- tion of keys early in the start-up process. Some of the common keys are DELETE, F1, F2, CTRL+ALT+S, CTRL+ALT+ESC. Often there will be a message like “Press F2 to enter Setup” displayed shortly after you turn the computer on. If none of the
