1 serial port 2 parity types? MFC based app needs assistance.

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello all

I am workiing in MFC on an app which has an odd requirement.. for me anyway.

I have only one serial port availbale. The task is that one portion of my
GUI has to send serial data out with EVEN parity. The other, a keypad, has
to send serial data out with ODD parity.

The reciever is always receiving ODD parity.

So.. unless I am wrong.. I am thinking I have to switch to ODD parity before
sending out keypad strings and tehn, when the last character is shifted out
I hvae to set the port back to even parity in time to get the host's
response.

Anyone have any ideas?


How do I query the actual output buffers of a port?

Can I set the com port's parity without closing and reopening the port?


Is this even the correct way to do it?

Thanks in advance

jona
