I am not sure whether the parity bit is typically the first one or the last one, and I don't think there is a fast shortcut to code this.

Hi Hilmar,
I'm not sure what that means. I am in need of transmitting a sequence of ascii characters to a web server that requires the message be as such (from their doc):
The raw binary packet must be formatted in 7 data bits/1 parity/even parity.
This seems to be similar to the older methods of data communications that one would have needed to use of com port transmissions to a modem. Isn't that something that would be possible and resources of information on it's creation be available?
