The  problem  is  that  the  files  listed  above  invented  a   new,
non-standard  mechanism  for something which is already available and
thus should be done in a different way.

See "board/netphone/phone_console.c":

    331         /*
    332          * Force console i/o to serial ?
    333          */
    334         if ((penv = getenv("console")) != NULL && strcmp(penv, "serial") == 0)
    335                 return 0;

Here you _do_ use an extra console variable.

Please get rid of this. Please the standard stdin / stdout  /  stderr
(here probably stdout) settings for this.

Best regards,

Wolfgang Denk
