So, if the 5200 series don't support TIOCMGET and TIOCMSET ioctl() (nor TIOCMBIS and TIOCMBIC, I've just tried them), what could I possibly use to get/set the control pin RTS in my Lite5200?... Is there any other system call or function that accomplishes that? Thank you very much. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
