[Trlog] TR and USB port on laptop

[Markhasin, Vitaly]

Hi All,
After many years of trouble free use of the program (well, almost) I've
loaded it on the laptop.
Laptop has a system commander with 3 operating systems:
DOS 6.22;
Win2000;
WinXP.
I'm using TRLog in DOS.
Laptop has only one USB port. How do you use this kind of computers with TR?
There are USB to COM port adapters available. Will they work? I need more
then one COM port
to control the radio, packet TNC and keyer (yes, I can use LPT for keyer).
Please share your experience.
Thank you.
