Thanks Stephen and Jerry, that helps. I just don't want to implement something
and then find out I am getting bad data, or else incomplete data.

Mark and space are the two possible levels of a single bit. Mark corresponds to
a logical 1 and in RS-232 is a *negative* voltage. Space is a logical 0, a
positive voltage. Parity is an extra bit tacked onto a word as rudimentary
error checking. 7 bits even parity uses the extra bit to make the

Hi all.
I noticed Sarah's stack has for parity, "None, Odd, Even". I am dealing with an
old phone system that uses "space" but there is also "mark". What is the
significance of this, and does parity even matter? I have the stack set to even
now, and have had it set to none and I still seem to
This worked famously Stephen, Sarah! I am really tempted to write a call
accounting app right now...

Hi all.
Has anyone written a serial port library? I would be happy to pay for it. What
I want to do is replace our call accounting software with something I write. We
don't need much, just departmentalized reports for charge backs, so I can do
that pretty simply in LC, but I am not very hip on
