Ten-digit dialing does not work
correctly under Windows 95.
Ten-digit dialing doesn’t work
correctly under Windows 95,
making it difficult to dial
numbers in a different area
code that are not long distance
calls.
Since Windows 95 does not limit the number
of digits you can enter in the Phone Number
field, set the Area Code field to match your
local area code. Then type the ten-digit
telephone number in the Phone Number field.
Modem cable
disables/interferes with other
telephony devices (Germany,
Austria, and Switzerland only).
The modem cable does not
provide the additional 4-wire
connection required in
Germany, Austria, and
Switzerland to form the serial
pass-through necessary so that
other devices can work on the
same phone line.
To use another telephony device on the same
line in these countries, unplug the modem
cable from the wall jack first.
Modem does not dial correctly
under Windows 95
(Switzerland and Germany
only).
The
“
Wait for dial tone before
dialing
”
check box is checked.
This causes Windows 95 to
issue an ATDT; command. A
typical dial string would look
like this:
ATDT;
ATDTnnn-nnnn
In Germany and Switzerland,
the
‘
;
’
dial modifier is not
permitted to be used in this
fashion by regulatory agencies
since ATDT; takes the modem
off-hook without dialing.
Therefore, the modem returns
an error message when
attempting to dial. The error
message reads:
“The computer is not receiving
a response from the modem.
Check that the modem is
plugged in, and if necessary,
turn the modem off, then turn it
back on.”
