Back in 2004, I bought a 2-port PCMCIA card made by Quatech, which has 
since been on a lot of Field Days, CA QSO Party county expeditions, and 
even a DX trip. It contains two real hardware serial ports and a 
pluggable dongle.  I've since bought two more for additional laptops.  
They are not cheap, Quatech is a US company, based in OH, I think.  I've 
observed no RFI issues, and they work with signal returns connected to 
DB9 connector shells.  .

In recent years, I've heard good things about Edgeport products.  They 
were not cheap until they went bankrupt a year or two ago.
