I have a hardware device that is sending a byte to the com port with a parity error.   The com port will not let this byte pass through.  I need to somehow ignore this and let the data pass through to my application.

HOW CAN I DO THIS?

Thanks

IMO, the parity settings for the device and com port should match, or you risk
your data being garbaged. However, you can have the device issue a "stty ignpar"
command to override this.

I tried that.. from the command mode before the application was started.  It did not help. We are also tryiing to do the same thing via code.  A line monitor
between the com port and the hardware device shows
the parity error and the byte does not get to the application.  I realize that this may cause garbage but until we get a hardware fix, we need something to
allow the data to be recieved.

Any other ideas?

It is still failing.  The external device is a tineclock where employees swipe a card through to "punch" in and out.
