FTDI USB/RS-232 Serial Cable


This is FTDI's premium USB to RS-232 serial cable in a 10cm length. It is the best USB to serial adapter I have found, and it works on most computers without needing special drivers.

This adapter is useful if you want to program a WP 34S (in conjuction with an HP programming cable) with a modern computer that does not have a serial port.
