I changed to BrainBoxes serial ports on PCI cards (UC-235) ... and haven't had any problems since.

…I would recommend a BrainBoxes PCI Express card or PCMCIA card. Brainboxes seems to be a forward-thinking company that has very strong driver support across its entire range, including some products more than 10 years old.

I really appreciate the support we have received from Brainboxes for our project, and hope that the business opportunities can continue.

Just to add I have also had issues with USB to RS232 adapters in general. In the end I went with a Brainboxes UC-101 and have had no further problems.
Actually took quite a lot of searching to even find the Brainboxes card since I needed one that supported both Windows 7, and Windows 7 64.
