On some systems the DSP has no DMA interface to the host and is
using a serial port for sending its trace. This patch adds a "-u"
argument to specify a baudrate, that should be used with the serial
interface. The implementation takes care of spurious bytes,
sometimes seen in the beginning of the trace, produced by the port
initialisation by the DSP. The format is fixed to 8N1.

1. Programs shouldn't exit with negative return values, strictly
speaking only EXIT_SUCCESS and EXIT_FAILURE should be used,
however it is also valid to return 0 for success and any number
from 1 to 125 for a failure.
2. Avoid passing complete structs as function parameters where an
additional copy of one isn't needed, use const pointers instead.
3. Remove a left-over unused argument.
