Re: really simple RS232-TTL converter... does it work?

Pure TTL out usually works, and just a series resistor for the input

Yeah, I've heard that. But the serial protocol is done in hardware on
both ends (my computer, the system-on-a-chip in the router), so I
couldn't use a non-inverting method. This trick with the MOSFETs does
seem pretty good to me...
