i have written an application that utilizes serail ports. In order not to
have to reinvent code, I decided to use John Hind's sample code that he
presented in MSDN magazine last year (Serial Comm: Use P/Invoke to Develop a
..NET Base Class Library for Serial Device Communications John Hind - MSDN
Magazine - October 2002)
it works fine except for one problem. i cannot address any port higher than
COM9. I am using an equinox multi-serial card that addes 16 serial ports, so
there are a total of 18 valid com ports. However when i try to open anything
over COM9: i get an error that says that it is an invalid name.
i llooked thruogh his code but was unable to find any reason why this would
fail.
does anyone have any explanations as to why it would fail or suggestions as
to how to fix this?
i appreciate your help
