Yes, several times though like Raymond says you may be stymied straight away
if your adapter is using a fake FTDI chip. Neither of my adapters work with
ADTPro largely because of the signals I think it's expecting to get with
regard to hardware handshaking. Also they're using CH340/1 chips which are
the Chinese FTDI clones.
Recently I tried setting up a Raspberry Pi using a genuine FTDI USB breakout
adapter that gives all handshake signals but couldn't get that to work
either and resorted back to my old faithful XP desktop with real 16550 UART
which works every time.
My next idea was to get a BusPirate to see exactly what signals were in use
on the real serial port but at the time BusPirates weren't available. Now I
see they are again so I might have another look.
