[RTTY] USB-Serial

Sometimes the Prolific chip set will work if you allow your Windows 
installation to search the internet for the needed driver. Here in 
Paraguay I could only find a converter cable with the Prolific chips. 
None of the supplied drivers worked, but as a last report I "allowed" or 
"asked" the Windows bit of software that was trying to do the 
installation to search for the best driver on the internet. After a 
considerable wait, it found and installed a driver that didn't seem to 
be uniquely for this chip set, but it worked. If you already have an 
adapter with the Prolific set, it might be worth a try.
