| Nov 14, 2014 at 20:43 | comment | added | Chris Stratton | It probably is possible to bit-bang serial at fairly high baud rates on a true localbus parallel port, if you write your own bare-metal program dedicated exclusively to that goal. It is probably not possible under a general purpose desktop O/S. | |

| Nov 14, 2014 at 20:30 | comment | added | user40669 | @WoutervanOoijen I was talking about buying one already made, which is about 20 bucks with shipping. Of course it's cheaper if you buy the parts and assemble it yourself but I prefer to avoid that. | |
