[WriteLog] Com port availability/access

[DanW]

Pardon me if this has already been posted:
I have a laptop wherein com1-com3 are allocated by system stuff (modem, 
etc..). No "real com ports" but USB and virtual com software allow me to 
create and use com 4-8. I control my Yaesu FT-2000 on com4, cw on com 5, 
RTTY on com7 and aux on com8. As I am a new Writelog user - I do not see a 
way to allocate Writelog to use com 4 thru 8. Ideas, suggestion would be 
greatly appreciated.
