I use a library called dzcomm which is an allegro add-on. It will allow you
to access up to eight com ports and supports shared interrupts. You can
implicitly open and close ports at any speed that your UART chip supports.
It is very easy to implement and has some good library functions for common
async serial requirements. Although there is an overhead with allegro it is
not too bad.

The user guide is a little hard going as the guy the wrote is Russian and
English is obviously very much his second language. Having said that, It is
all there and seems to be pretty much bug free.

If you are interested I suggest you check out

You can get Allegro from DJ's zip picker, if you don't already have it.
