[WriteLog] USB / Serial converters

[K1DW at aol.com]

Am trying to interface CW, RTTY, PTT and Radio Control using Writelog  
(version 10.36G) in a SO2R configuration.  My computer is a Dell 4500 running XP 
with only two USB ports.  Right now I am just trying to get one  USB working with 
a CW, PTT and RTTY interface. Then will expand to other  features.  I built 
the AA5AU serial  interface and am trying to get it working with one USB / 
Serial port converter  (BELKIN F5U109).  I want to use FSK  rather than ASFK for 
many reasons with PTT and CW with the PTT feature.  
1)      How do I configure the Setup in Writelog for using  USB / serial 
converter? 
2)      In the future can I use a USB 1 to 4 expander to  create additional 
USB accessible ports with the appropriate USB to serial  converters? 
3)      Will the expander control two radios (frequency /  band) and two USB 
/ serial port converts to operate two CW, RTTY and PTT  interface? 
4)      Is this overall plan feasible or over ambitious?
