Una cineseria che presi diversi anni fa, un HL-340 ma non so che chipset monta, probabilmente un CH340.
Fatto sta che ha i livelli TTL invertiti e non è utile a niente.

Cercando in rete ho appena trovato questo:

"The actual chip is probably a CH340 (the 341 also supports a parallel port). It may be some other chip compatible with the CH340.
There are two versions of the CH340. One is intended for use with RS-232 drivers and receivers, such as the MAX-232. The other version uses the opposite logic levels on the I/O's and is intended for use with infrared links."
