Aura H2O How to get messages from the serial port ?

[sahbi]

hello everybody,
has someone succeeded getting something out of the serial port of the aura h2o ? I've attached a uart usb to the J5 port, crosscompiled the g_serial module, managed to insmod it, and use minicom or putty to get something, but until now failed, the tx rx leds are blinking sometimes but nothing reaches the console. Thanks for some help.

Does this thread help? https://www.mobileread.com/forums/sh...d.php?t=243647

Thanks Peter, I already know that thread and all other threads about connecting a uart usb to a kobo(but no H2O), found also other blog entries.
I describe here what I've done until now maybe it helps others:
1. put this at the end of rcS (needed for telnet)
mkdir -p /dev/pts
mount -t devpts devpts /dev/pts
2. and this in inetd.conf (start 2 daemons)
21 stream tcp nowait root /bin/busybox ftpd -w -S /
23 stream tcp nowait root /bin/busybox telnetd -i
3. this goes in inittab
::sysinit:/etc/init.d/rcS
::respawn:/sbin/getty -L ttymxc0 115200 vt100
::ctrlaltdel:/sbin/reboot
::shutdown:/bin/umount -a -r
::restart:/sbin/init
::respawn:/usr/sbin/inetd -f /etc/inetd.conf
compress all in a KoboRoot.tgz, connect the H2O, deposit KoboRoot.tgz in .Kobo and let the reader upgrade.
Now I have telnet access to insmod g_serial.ko that I have cross compiled with the linaero toolchain, insmoding g_serial.ko gives an error, dependencies problems, could cirmumvent this by insmoding first arcotg_udc.ko.
Attached the "uart usb" to the host, dmesg says it's connected to ttyUSB0, configure minicom for ttyUSB0, 115200... now between "uart usb" RX to TX, TX to RX and GRND to GRND.
what now ????

Just for the record, during an intense and baffling second, when I read the title of the thread, I thought it said:
