Hi!!.. I read your post on http://lists.freebsd.org/pipermail/freebsd-questions/2011-August/232945.html, and I have a similar problem. I my case I try to set and unset the RTS pin of the serial port, I use the ioctl() function with the TIOCMGET and TIOCMGET, the program works very well when I use the serial port (COM1) but when I use a USB<->COM (like you) converter the ioctl() function return me a fail, the error is "Invalid Argument". I need some solution or if you can recommend me any page or put me in contact with any other person. Any help will be very useful. My name is Juan Rodriguez and I'm from Paraguay. Thanks!!. P.S.: Sorry my English is not very good.
