Alternatively one could build/write a multiport serial port solution. If 300 bits/sec is enought it should be possible to build hardware with lots of serial ports based on the parallel port. Once done, it would definitely be cheaper than a stack of USB serial ports.
Basically you would have an interrupt timer running at several times the baudrate. It polls the state of all serial lines via a relatively simple hardware.
If there's some interrest, I can try to think more about it. I think I have the parts lying around.
