See the note below about Plug and Play modems.
Windows 95 or Windows 98
If you are using Windows 95 or 98 and your modem is working,
but you are unsure which Com port your modem is using,
open the Windows Control Panel and double click Modems.
In the dialog box, choose the modem and click Properties.
The COM port will be displayed next to the word "Port:".
To determine the interrupt (IRQ) for the port, go back
to the Control Panel and double click System. Click the
Device Manager tab and double click Ports in the list.
Choose the port and click the Properties button. Choose
the Resources tab. The Interrupt Request setting is displayed.
Note: In recent years, some modem manufacturers have
introduced modems that require proprietary Windows software and
will not work with DOS-based programs like NewDeal. Some of these
so called "Win-modems" will not work with NewDeal software.
Generally speaking, if the modem will work with DOS-based
software, it will work with NewDeal.
Plug and Play modems
The port and interrupt for Plug and Play modems are determined
by one of the following:
- your computer's CMOS
- a DOS driver, probably loaded in your AUTOEXEC.BAT file
- a driver in Windows 95 or Windows 98
Consult the documentation for your modem or ask the manufacturer
of your modem to determine how and where to change the port and
IRQ settings, if necessary.
Note: In some cases, the port and interrupt settings for
Plug and Play modems may change when you reboot the computer
or when you add peripherals or change your computer's hardware
or configuration.
PCMCIA modems
Many modern notebook computers, and some desktop computers, use
PCMCIA modems. A PCMCIA modem is a small card that you insert
into the PCMCIA slot, sometimes called a "PC slot" or "thin
card slot."
PCMCIA modems require special drivers, similar to Plug and Play
modems. If NewDeal is unable to find or use your PCMCIA modem,
you might need to load the DOS drivers for your PCMCIA slot.
Check with the manufacturer of your computer or the PCMCIA slot
to see if DOS drivers are available.
Controllerless or Windows-only modems
In recent years, some modem manufacturers have introduced
inexpensive modems that work only with Windows applications and
do not work from DOS. The intelligence in these modems has been
removed, lowering their production costs, and they require special
Windows drivers provided by the manufacturers to compensate for
the interpreter that has been removed from the modem. These modems
will not work with DOS programs like NewDeal.
ISDN modems
Generally speaking, NewDeal does not support most ISDN modems.
However, some customers have been able to use their ISDN
modem, if the modem is fully Hayes compatible.
Cable modems
As of this writing, NewDeal does not support any known cable modems
directly. One possible work around is to set up a network
server connected to the cable modem, and then use the
ODI Ethernet driver to connect to the Internet from
workstations on the network that are running NewDeal software.
