Black Box MD1641A Phone Number Memory Commands, Storing Phone Numbers D...N, Number Linking NN

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”.
