Type "ATZ <CR>". Sometimes you may not see
anything. Wait a second or two and type "AT&F <CR>",
followed by "AT <CR>". If you get an “OK” message,
then the installation works properly. If you get an error
message from Windows 95 or if the modem does not
respond with an “OK” message, then either you have a
IRQ conflict or the .INF file was not installed properly.
Look at the section entitled “Installation Problems,”
which appears later in this chapter.
Note that you can download subsequent firmware into
the modem without repeating the installation process;
however, you cannot do this if you have downloaded
new features not supported by the modem you selected
in the previous installation. It is recommended that you
remove the old Windows 95 modem setup if you repeat
the installation process for the same modem.
Installation Problems
COM Port Address and IRQ Hardware Conflicts are
some of the most common installation problems. They
occur when more than one modem uses the same COM
port or IRQ. Additionally, other devices, such as the
mouse and sound card, may also use conflicting IRQs.
To check for a hardware conflict, you must first enter
DOS mode. Restart Windows 95 using the Restart to
DOS function in the Shut Down menu. Next, start any
DOS terminal emulation program such as PCPLUS. Try
sending AT commands to the modem.
