There are bound to be some errors

A couple of questions/comments.

1. The 82164A is jumpered for DTE mode?

2. A USB-to-Serial adapter won't work with the 82164A's RS-232 interface. You'll need an adapter with inverted RS-232 level signals.

3. As the adapter won't plug directly into the 82164A, a null modem cable is usually be used. Can you provide details on how this cable is wired?

Thanks,
Dave
