signed vs unsigned int

i'm reading bytes from a serial port, and storing it into an array. each byte represents a signed 8-bit int. currently, the code i'm looking at converts them to an unsigned int by doing ord(array[i]). however, what i'd like is to get the _signed_ integer value. whats the easiest way to do this?
