tone. In that case, the modem may not recognize the dial tone and may treat
it as an error. Check your PBX manual to see if you can change the internal
dial tone; if you can’t, change your modem’s initialization string to replace
X4 with X3, which will cause the modem to ignore dial tones.

If the modem reports
BUSY, the other number may be busy, in which case
you should try again later, or it may indicate that you have failed to add
a 9, prefix to the phone number if you must dial 9 for an outside line.
If you must dial 9 to get an outside line, the easiest way to dial it
automatically is to include it in the modem’s dial prefix, e.g., ATDT9,. Note
the comma, which inserts a pause before the number is dialed. By inserting
9, into the dial prefix, you do not have to include it in each directory entry.
To change the dial prefix in your communications package, select
Setup,
Modem; then select the modem type you are using, and type the new prefix
in the Dial Prefix box. To change the dial prefix in Windows Terminal,
select
Settings, Modem Commands.To change it in Windows 95 Hyper-
Terminal, select
Call, Connect from the menu bar, click Dialing Properties,
and type 9 in the local and long distance boxes in
How I Dial from This
Location.

If the modem reports
NO ANSWER, the other system has failed to go off-
hook, or you might have dialed a wrong number. Check the number.

If the modem reports
NO CARRIER, the phone was answered at the other
end, but no connection was made. You might have dialed a wrong
number, and a person answered instead of a computer, or you might have
dialed the correct number but the other computer or software was turned
off or faulty. Check the number and try again,
or try calling another system to make sure your modem is working. Also,
try calling the number on your telephone. If you hear harsh sounds, then
another modem is answering the call, and the modems may be having
problems negotiating because of modem incompatibilities or line noise.
Try connecting at a lower speed.

If you have call waiting on the same phone line as your modem, it may
interrupt your connection when someone tries to call you. If you have call
waiting, disable it before each call. In most telephone areas, you can
disable call waiting by preceding the telephone number with
*70 (check
with your local telephone company).
You can automatically disable call waiting by including the disabling code
in the modem’s dial prefix (e.g., ATDT*70,—note the comma, which
inserts a pause before the number is dialed). To change the dial prefix in
your communications package, select
Setup, Modem; then select the
modem type you are using, and type the new prefix in the Dial Prefix box.
