Syl,
Bingo.
I defer to N4ZR, KD4D, N6TV and other gurus on this reflector but from what
I've seen, virtually none of the USB-LPT interfaces are good for more than
printer connections. That's why PIEXX developed the SO2Rxlat to translate
between USB and a virtual LPT.
I have one, it works in N1MM and WINTEST - both of which have implemented
the MK2R protocol (at least the radio and headphone switching does, I've not
been able to get it to send CW through the LPT yet) - but not at all with
TR4W (unless there's a beta version out there compatible with MK2R, rumored
to be in the pipeline a year ago).
Another future possibility is incorporation into TR4W of the YCCC box or the
new micro2R box, both of which are roughly the price of a DX Doubler (230
euros for the latter).

I have been running TR4W in SO2R with a DX Doubler for nearly a year.
However, I am using a computer with conventional parallel ports. I am
considering moving to a different machine and using USB-parallel interfaces
instead.
Are all or just some USB-parallel interfaces not able to toggle pin 14?
tnx
