• When using a modem connected to a private branch exchange
(PBX) or TA, you may not be able to hear the dial tone (i.e.,
sound you hear after picking up the telephone receiver). In that
case, suffix "X3" to the AT command.
• When making a call from an extension to an outside line, or to
dial a number after dialing 0, enter "0," (zero and a comma)
before the telephone number as in "0, ??????????." This keeps
the phone waiting a certain time.
Any type of modem (e.g., RS-232C, USB, PC card) can be used on
the PC side when using a public switched network or cellular
phone, provided that it is compatible with your PC.
