 		 #145592 - Level converter
Responding to: ???'s previous message
It translates between the voltages used by the PC serial port (+/- 12V, iirc ?) and the voltages used by your chip (0 and 3.3/5V, for example).

Hooking up the chip to the PC serial port without a level converter will probably fry the chip.
