[Trlog] usb to rs232 multiport adapters

[john, ke5c]

has anyone successfully run tr-log on a laptop using one of the newer
usb to rs232 adapters such as:

http://www.bb-elec.com/product_multi_family.asp?MultiFamilyId=5&TrailType=Sub&Trail=31

these devices often state they are win 98 compatible.  i am planning a
new notebook, and most no longer come with any serial port.  moreover,
i need at least two and probably three, so i am thinking a solution
would be a dual boot win98/xp system and a usb to rs232 multiport
adapter - if those devices will work with tr-log.  if i run tr-log in
a dos window under win98, it would seem possible the win98 device
drivers would make the multiport rs-232 ports available to tr-log, but
i just wonder if anyone has tried this?
