[ECOS] Problem with getchar / gets / fgets

[Nicolas Brouard]

I'm using eCos from latest CVS repository, in default configuration. So I'm
using:
CYGPKG_IO_SERIAL_TTY = 1
CYGPKG_IO_SERIAL_HALDIAG = 1
CYGDAT_IO_SERIAL_TTY_CONSOLE = /dev/ttydiag
CYGPKG_IO_SERIAL_TTY_TTYDIAG = 1
Others options of component CYGPKG_IO_SERIAL are no active or default value
are 0

What is the real serial driver?

I'm not using GDB. I just launch my shell application with redboot and
communicate with my shell with minicom (as same as redboot).

What serial driver are you using? haldiag or the real serial driver?
Is the port being shared with gdb or is it a dedicated port?
