Edgard,

II have used NT Port from Zeal Soft Studio (www.zealsoftstudio.com) for
about 3 years.
NT Port works with Windows 95, 98, NT and 2000 and allows access to any
addressable port.
NT Port is a professional quality product with good customer support.
You may download a demo or you may purchase NT Port for $30 which is a
small price for reliable bug free port access.

Sincerely,
Ned Seith
