RS232-7 data- even parity- 2 stop

[manie]

Could I read rs232 with 7 data bits, even parity and 2 stop bits at 4800 baud, using Picaxe 28x1 or 28x2 ?

What would the Serin command look like then ?

If not, is there some form of convertor available to convert to standard Picaxe Rs232 ?

As always, your input highly valued...

Non standard RS-232 protocols normally mean tedious "bit banging", but Hippy suggested a simple 7 bit approach just on a month back. Check post #4 of => http://www.picaxeforum.co.uk/showthread.php?t=13002

Of course, especially given your apparent panic, you could amplify as to WHY THE NEED.

Reading 7-bit data with odd/even parity and 2 or more stop bits is easy; simply mask off the msb of the received data to get rid of the parity bit. The extra stop bit(s) don't matter as they just appear like normal gaps between consecutive bytes.

SerIn pin, baud, b0
b0 = b0 & $7F

Lets close this thread and start a new thread on the project relating to these questions regarding data bits, distance measurement etc.

Thanks to all, the new thread will explain my NEED ! Look for:

Accurate plus Precise distance
