I recently purchased a commodore 64 with a vic-modem. I had hoped to use it partly for working at home over the phone lines instead of dragging a silent 700 home with me. I also work for WEco. and had just purchased a brand new wall phone- touch tone, that worked just fine with the silent 700. I brought home my vic-modem (direct connect) and I couldn't get the remote cpu prompt even tho I got carrier. I tried another wall outlet and the same occurred. I took the processor, software and modem back to the commodore store and it all worked fine with their phone. I couldn't believe that my shiny new western phone was at fault. Finally, I took home my work phone and found out that the problem was with my wall phone. I found a refurbished GTE phone ( which one of my friends has to rewire since it has hardwired and I needed a modular jack ) which is now working just fine. So, if you have modem problems, try a different phone. I was surprised... ricki simon - ihuxl!rs1

I have an auto dial modem that uses pulse dialing (not touch tone) [Cermetek] and found that with a new phone I purchased that the auto dial function no longer works. This is a phone that has redial capability, etc. and my guess is that it's powered off the phone line. When I use the modem to dial, it pulses the line, and thereby power cycling the phone on and off, and somehow disrupting the line. It seems my only solution is to get rid of the phone.

I had a similar problem with my modem (Racal Vadic VA3451AD) as that reported here and earlier: it would work fine without the phone or with a friend's Radio Shack hand-held, but it wouldn't work with my touch-tone phone. After mucking around, I finally found the problem, which may be a common one. The telephone and modem only use two of the wires in the 4-pin connector. The modem considers the other two to be a data control signal. My phone didn't do anything with these wires, but it did have them both attached to the same otherwise unused screw terminal - it had connected them together. I moved one of the wires to another unused terminal, and the problem with the modem vanished. Ma Bell, etc. would prefer you didn't fiddle with your phone, so you can do the same thing by cutting one of the wires in your modem cord (or disconnect it inside the modem). Hope this helps.

Ricki, There is also a problem with the newer WECO touch-tone desk phones. The ones with the "chicklet over membrane" keypads. You can tell these by the lack of travel of the keys. The Vic-Modem does not work well with these models. Frank Brown

We have some Vadic 3451's around here that were purchased about a year ago. The ones which were ordered with the normal house-style jacks came with a 2-way adapter with slots labelled "phone" and "modem". The "modem" side had only two wires present, thus preventing the connections on the other two from affecting the modem in any way.

From: Ron Natalie <ron@brl-bmd> Vadic modems come with a 2-for-1 modular adapter plug for attaching a phone and the modem to the same outlet. The two holes in it are not the same. The one labled modem only has the center two wires (red/green) passed through. -Ron
