BIOSCOM as the name says, uses the BIOS functions which are simple polling functions. You will be lucky to receive reliably even at 9600 baud. For higher speeds you need to use interrupts and need an ISR, perhaps even a dual Protected Mode/Real Mode one. Hyperterminal uses the Windows kernel-mode driver, so there is no comparison.
