[ECOS] How to add a 4th termios driver?

[ECOS] How to add a 4th termios driver?

[Tim Hatton]

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
Tim Hatton

% find /work2/ecos/packages -name "*.cdl" -or -name "*.h" | xargs grep CYGPKG_IO_SERIAL_TERMIOS
/work2/ecos/packages/io/serial/current/cdl/termios.cdl:cdl_component CYGPKG_IO_SERIAL_TERMIOS_TERMIOS0 {
/work2/ecos/packages/io/serial/current/cdl/termios.cdl:cdl_component CYGPKG_IO_SERIAL_TERMIOS_TERMIOS1 {
/work2/ecos/packages/io/serial/current/cdl/termios.cdl:cdl_component CYGPKG_IO_SERIAL_TERMIOS_TERMIOS2 {
/work2/ecos/packages/io/serial/current/cdl/termios.cdl:cdl_component CYGPKG_IO_SERIAL_TERMIOS_TERMIOS3 {
/work2/ecos/packages/io/serial/current/cdl/io_serial.cdl:    cdl_component CYGPKG_IO_SERIAL_TERMIOS {

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

OK, got it working. Thanks for that (don't know why my Windows search didn't
find that file).
