Null Phone Adapters for Sale

IMG_4031I am currently selling adapters that I have built that allow you to connect two computers together via modem’s without the need for any phone service. These are very simple to use:

  1. Plug phone cables into the adapter from the 2 computer’s modems
  2. Plug 9volt battery into adapter

From here you would just use the terminal programs (or BBS programs) you have on the 2 computers to get them to talk to each other.

IMG_4029If you want a more permanent solution than the 9 volt battery you can replace it with a DC adapter, red is positive (+), black is negative. I have tested it with voltages from 4.5 volts up to 12 volts though I recommend sticking with 9 volt.

If you want to build one yourself you can look at this webpage for the details on how it works ( Parts wise you will end up spending about the same as I am selling them for.

    1. Maybe – it just replaces the need for a phone line. You would want to use the AT command ATE1X1 to tell the modem on your PC to echo commands back to you and to also ignore the lack of dial tone. Then do ATDT1234 on the PC to dial and your Atari should auto answer if you have the BBS setup correctly. If you have a Hayes compatible modem on the Atari you may want to put in the ATX1 as part of the setup so that it ignores dial tone also.

      If you want to use your PC as some gateway to other systems that you can access via your Atari, as long as you can do it with a normal phone line you can do it with this.
