Oh yeah,

Since I din't make this clear, and since it was your original question, using the UART (Universal Asynchronous [sic?] Receiver Transmitter) for ISP (In System Programming) shouldn't require a special cable. If, of course, you don't make the Tx-Rx crossover in your circuit, you might need a null modem cable, but even that won't be true as long as you lay out the connections correctly.

Again, Good Luck.
