As someone already mentioned, reading the termio man page
(on IRIX versions 6.3 and newer) will explain how the
termio structure changed.
You can define _OLD_TERMIOS at compile time and use the old
format.
You can use old binaries with new versions of IRIX and they
will still work using the old interface.
If you use the new format with current IRIX versions, then
your binaries won't work on older IRIX versions (pre 6.3).
Here is how you can code it if you with to support both
formats:
struct termio tio;
#ifdef __NEW_SSPEED
tio.c_flag = CREAD | CS8 | CLOCAL | HUPCL;
tio.c_ospeed = B19200;
#else
tio.c_cflag = B19200 | CREAD | CS8 | CLOCAL | HUPCL;
#endif
Or, you can define _OLD_TERMIOS and just use the old
structure.

Yes, this is correct. The old binaries will still work on the new
IRIX versions.
