Re: How to add a 4th termios driver?

Hi,
I am currently in the process of building an application witht eCos (2.0.43) running on our own hardware which uses an ATMEL AT91RM9200 CPU. I am trying
to add a 4th termios tty driver (i.e. /dev/termios3) but haven't really
succeeded.


I thought this would be a simple case of editing some CDL files but I can't
work out where the current CYGPKG_IO_SERIAL_TERMIOS_TERMIOSn and
CYGDAT_IO_SERIAL_TERMIOS_TERMIOSn_DEV definitions are.

If anyone could provide some ideas I'd be grateful.
Best regards

You'll also need to change /work2/ecos/packages/io/serial/current/src/common/termiostty.c
where the TERMIOS structures are [manually] enumerated.
