Adding inbyte, outbyte to libgloss

[russell]

Hi all,

I'm trying to add serial-port stdin/stdout support for the
hitachi H8/300H cpu.

I read porting.texi in newlib-1.8.3/libgloss/doc, and
configure.texi in newlib-1.8.3/etc, but things are still
unclear.

When i do "../newlib-1.8.3/configure --target=h8300-hms",
i get:

Configuring for a i686-pc-linux host.
*** This configuration is not supported in the following subdirectories:
     target-libgloss
    (Any other directories should still work fine.)
Created "Makefile" in /home/russell/newlib


I can get rid of this by deleting target-libgloss from line 676
(noconfigdirs) of newlib-1.8.3/configure.in. Should i do this so
i can add stuff to libgloss?

I assume next i should add a directory such as
newlib-1.8.3/libgloss/h8300 with these files:

CVS/         configure*    crt0.S    outbyte.c
Makefile.in  configure.in  inbyte.c  syscalls.c   

Anything else to do?

Do i need to redo inbyte/outbyte, or read/write as well?

I'm using the H8/3048F in my own setup with eproms and
no gdb or monitor stuff.
