Welcome to America!
That's theoretically possible, but no serial drivers have been written yet. USB actually does have a serial standard, but almost none of the manufacturers follow the standard -- they come up with their own proprietary way of doing things. So, if you buy a USB-to-serial adapter made by one manufacturer and write a driver for it, it may only work with that one particular manufacturer/model. I do intend to write a serial driver someday (and it probably won't be very "universal" for the reason just mentioned), but even at that it will still be a long time in the future.
I think in the past you used FreeBASIC, and you might be able to leverage what you did in the past and write a serial driver, at least for a specific manufacturer/model of adapter (assuming you can find enough information about how their protocol works). Hopefully the hardware you're using still has UHCI host contollers so my drivers will work -- modern hardware has gotten away from that.
