Best trick is to cascade a MAX3232 level shifter with 3V3 power supply. It will raise the signal level to just over 5V. That is enough for the average serial-to-USB converter. It also protects the other end from over voltage. I once had to couple an AVR32 development board to an automotive GSM modem using a bi-directional cascade of 3V3 and 5V powered MAX3232 level shifters...
