Hi Dave

1. Yes the HP-82164A is DTE. At least it appears to be when I opened it yp.
2. Correct
3. I have a 15 pin female ended (both ends) null model cable; one end connected to the end of the USB to serial cable; the other end to a simple 15pin to 25pin adapter which is connected to the HP-82164A.

I did wire up a cable like that suggested by Christoph Klug & J-F Garnier, April 2006, based on previous material from Tony Duell but the null modem worked just the same from memory? I did not wire the null modem, it came straight from the shop.
