so the picaxe can detect the "0" information
it can detect that an information is not a zero
but it doesn't recognize the "1" information

If all you are wanting to send from the PC to the Picaxe is a simple 1 or 0 it would be easier to do that with one of the RS232 status lines instead of data over Rx/Tx.

Hi,

Your (wrong) code is setting "Port 1" High, but clearing "Port 0" to Low.

But you really should be using the Port.Pin format now, e.g. Low c.1 for modern PICaxes.

Cheers, Alan.

hi
answer to lewisg :This programm is just the begining. After i want to send complex data. that's the reason why i use rx/tx
answer to allycat:you're right i'm testing this program whith an old 28x1. But it doesn't explain why it can't read the binary "00000001" value

All PICAXEs apart from the X2s default to 4800baud for SERRXD, see manual2 page 207.

What baud are the characters being sent to the PCIAXE at ?

Its often not as simple as that.

For two devices to communicate successfully on SERTXD, you need to ensure that the baud rate, polarity and start and stop bits are the same for both ends of the link.

So if it does not work, you can always check the manuals to see what the default settings are.
