Not POTS then?  My ASR-33 with Data Set is totally POTS.  I tested it
by dialing up CompuServe.

I'm restoring a number of Model 15s and Model 19s and a Model 14 for a
friend.  I'm aware of 120VDC 60mA current loops.  The ASR-33 is 20mA @
12VDC (or so).  You are saying that the selector magnet in an ASR-32
pulls 60mA?
