[NTLK] NewtonTalk Digest, Vol 62, Issue 19

[Allen Russell]

This web site shows that DTR and DSR pins are used.

It also says the connection weren't tested.  It may be worth adding those two pins, jumpering them so DTR and DSR is always high.

>I decided before investing in mini din 8 to DB9 cable that is longer than necessary, I'd try to slice one together from what I've got. I checked the continuity of my >cables, cut off the ends and tested which pins go to which wires. I found a pin mapping and spliced them together. The result was less the a foot long. Perfect. I >tested the continuity again and the connections were good.
>But it didn't work. I know my Ser-001 is good, as I used to connect a Stowaway keyboard to my Newt. I think the problem is that the DB9 cable only had three >wires, ground, Txd and Rxd. For standard serial that should be enough. Does the Newton use other pins? Is it possible that I need to re-seat the Ser-001, even >though the ketboard works?
>The cabling solution I have now uses the Newton Connect port since I don't have a mini din 8 to DB9. I would loike to get away from that.
>Thanks!
