I think I have a rough description of the hardware serial random generator I want to build. I want to call it the "Rander box" for lack of a better name.
It will have two serial connectors, one an input, and other the output, and connect to a modem or serial port. Physically, it should have dip switch to select baud rate, and an on-off switch.
When switched on, and a "cr" (or some other character) is sent to it, random bytes will stream out continiously. Another "cr" will stop the byte stream. At least this is ONE approach. If anyone can think of a better way, Pse speak up.
Why two serial connectors? RS232 is bidirectional, so you could send control signals down the same pipe the output comes off of. Also, why bother decoding the CRs? Seems like overkill. You could just have CTS/RTS or other lines on the connector control whether bits are clocked out or not. Perry
