I've tested several of the USB serial ports (Belkin, BlackBox, etc.)  Most
work for some applications, but not all applications.  

The only one I've found that works perfectly for *all* apps is Keyspan Model
#: USA-19HS.  See
http://www.tripplite.com/en/products/model.cfm?txtSeriesID=518&EID=13384&txt
ModelID=3914.  Fortunately, they are inexpensive and available everywhere.

====================

Does anyone know of a single channel USB to 9 Pin Serial Converter that 
will work on RTTY?  I know they are getting very hard to find because of the
5 
bit keying.    I picked up an IOGEAR USB / Serial interface  today.  It 
drives the PTT just fine but not the FSK line.  I do have a 4 channel PCI
board 
from SIIG.  It works fine for radio control but actually crashes when I try 
to access it from MTTY.  Of course, my on-board COM port works fine for 
everything.  
 
So what I really need is just one more port and a single channel USB to 
Serial port would be the ticket if I could find one.
 
Am using Windows XP.
