SERIES II INTELLIGENT DATA/FAX MODEMS
for at least one ringback and 5 seconds of silence. If a busy signal is
detected, the Series II Modem hangs up and generates a BUSY result
code. If it does not detect 5 seconds of silence, a NO ANSWER result
code is generated after hanging up. If 5 seconds of silence is detected,
the second number (746-5500) is then dialed.
5.4.3 Phone Number Memory Commands
Storing Phone Numbers D...N
A telephone number and command line of up to sixty characters may
be stored in the Series II Modem’s number memory. As many as ten of
these numbers may be stored. Each number will be given a name, using
the codes N0, N1, N2 up to N9.
A phone number is stored by entering ATD, then the number as it
would be dialed, along with any P, T, R, ; or comma characters, and
then entering N followed by the number’s “name,” which would be
any number from 0 through 9, and then hitting RETURN.
For example, the tone-dialed number 1-612-631-3550 would be stored
as number N3 by entering ATDT17247465500N3 and RETURN. The
number is not dialed with this store command. After storing a number,
check to see that it has been stored correctly by typing ATL and hitting
RETURN.
When phone numbers are stored, the entire command line is also
stored so that you can effectively create a macro for each number. For
example, if you know a particular number needs to have extended
result codes, detect busy or dial tone, error correction, Xon/Xoff flow
control, pacing, and data compression enabled, the command line
would be:
ATX4&E1&E5&E13&E15DT17247465500N3
This would store the entire command at location N3.
Number Linking NN
You may command the Series II Modem to dial another number
automatically if the first number dialed is busy. This would be useful in
a situation where a computer can be accessed through more than one
phone number. This is called “linking”.
