Hello Mal,

QRS doesn't work with a "pure" USB port. Unlike the serial and
parallel port the lines of a USB port cannot be used as "switch
signals" (or at least I haven't found out how to do so), it are real
communication lines.
However there should be a simple workaround: a USB to RS232 adapter.
This adapter includes some hardware and software, the last making "to
believe" your PC that there is a RS232 port. These adapters cost about
20 Euro in the shop and I've seen them as low as 5 Euro on flea
markets.
I don't know if someone already tested one of these adapters with QRS?

Hello Rik / Mal.

Yes, I use my laptop with MMSSTV PSK31 QRS etc. So far, all work well using a USB to serial converrter.
