plip: StdOut > ttyS0 & ttyS1 > StdOut

Avoid9Pdf · 2013-04-02T14:36:59+00:00

The rPi credit-card-sized ARMbased computer which is already widely distributed, has no facilites to drive VGA. It has however a GPIO port [?IEE488]. A driver for RS232 would be easy to drive the GPIO port. I think plip is even simpler, and there's linux info for it. Would it be viable to:- connect the rPi's port to a PC's RS232-port, rPi redirect StdOut to ttyS0, PC redirect ttyS0 to StdOut ? This would allow one Terminal of the LinuxPC to show the rPi's output -- hopefully. I've got a crossover-cable RS232 to RS232. Could I test the concept on a PC which has 2 RS232 ports, with one port simulating the rPi? == TIA.
