The BIOS functions only support baudrates up to 9600. For higher
rates you need to program the UART directly.

Why ``stuck''? IMHO, bcserio is a good library.
Anyway, you don't need a library if you don't want interrupt-driven
communications. If your application can settle for polling the UART,
you can simply initialize the UART for your baudrate, and the read and
write its ports to send/receive characters. This is very simple and
should not require any library.
