Finding A Modem Initialization String

Recently a younger brother asked me to assist him in getting a computer. It was delivered here in Arkansas and he visited from Florida to get some initial instruction about his machine.

The computer was from ARES and had a 56 K FAX modem with voice. The modem was manufactured in Taiwan. JUNO was being installed when a problem was encountered. JUNO could not find an initialization string it could use to connect this modem.

The solution was provided by WINDOWS. It seemed reasonable to assume that if WINDOWS recognized the modem it might have the initialization string it used stored in the registry. Prior frustrations had taught me that initialization strings always began with "AT&F."

The registry was searched by:

1. Clicking on RUN,

2. Entering "REGEDIT" (no quotes) as the program to be run,

3. Clicking on EDIT,

4. Clicking on Find and

5. Entering "AT&F" (no quotes) as the phrase to be found.

There was quite a wait. The registry is a large file. After a bit a new screen popped up and on the right hand side one found,

AT&FE0V1S0=0&C1&D2+MR=1;+DR=1;+ER=1(cr)

This string was entered for JUNO, the (cr) being a carriage return or ^M. JUNO liked it just fine.

This manner of finding a workable modem initialization string works in both WINDOWS95 and WINDOWS98. It does not work in WINDOWS 3.11 where REGEDIT brings up a Registration Info Editor. This latter has a listing of registered file types.
