Details:

It turns out the variable "len" which is used to control the
loop is never assigned.

Good item to demonstrate why you'd rather *not* blindly
initialize all local variables by default in their definition,
like:

static int ser_recv(union filedescriptor *fd, unsigned char * buf, size_t
buflen)
{
        unsigned char c;
        unsigned char * p = buf;
        size_t len = 0;
                   ^^^^
