The serial data is returned in a cyclic buffer which MUST be allocated
by the caller. The caller specifies the location and size of the
buffer in buf and bufSize.
The serial data is returned in a cyclic buffer and is read using
gpioSerialRead().
It is the caller's responsibility to read data from the cyclic buffer
in a timely fashion. Data is available when readPos is not equal to
writePos.
EXAMPLE:
#define BUFSIZE 1000
char buf[BUFSIZE];
int bytes, wpos;
FILE * outFile;
gpioRx_t rx;
...
rx.buf = buf;
rx.bufSize = sizeof(buf);
