Writing to Serial Port; Handshake.None Not Taking

Question

I am trying to use System.IO.Ports to write to a serial port but cannot get it to recognize Handshake.None. I can use a terminal program with handshake set to none and see that it is working using PortMon. The same thing using .NET does not work, PortMon shows that the handshaking is still on even though I am setting it to None in code. The device I am writing to does not work with handshaking and I can operate it just fine with the terminal. I am actually using a USB to Serial Adapter (a cheap one with no name.) Should I get another adapter from a name brand (and better driver) or should I give up on .Net and rewrite using some API comm calls?
