ATE1 (((this one invisible, you need to type blind.

OK
at%sleep=1
EXT: I
OK
ATE1 is enabling instant echo from calypso, which I find much more convenient
(same as the char-wise input by -c parameter to mickeyterm)
at%sleep=1 stops the annoying 10sec timeout that makes you enter every command
twice.
All this on GSM-flashing uSD-image booted from uSD, login via ssh.
you might want to
r...@om-gta02:~# ps x
1645 ? S 0:00 /bin/sh /etc/rc5.d/S99flash-moko start
r...@om-gta02:~# kill 1645
to stop the gsm-flashing process (if you're sure FLUID isn't just about to
flash the GSM-FW. I.e: if it shows either "Bootloader: (reset target)"
or "Program: (0 sectors, 0*8k=0k) () ok" it's absolutely safe to kill the
flashing process)

I really wonder whether your battery is ok. You know modem is powered from
battery and when it starts to transmit for registering to the network it
demands quite some power from bat that can't be provided by bat-charger chip
PMU. So it's very likely modem would reset due to brownout as soon as it
tries to register to network.
Please try and find a spare bat (see wiki for compatible bat e.g. from nokia
if you can't manage to get a GTA02-bat). See if modem behaviour changes
significantly with new bat.
I'm really sorry you have such an extended period of problems with your FR's
modem. Hope we will track it down now.
HTH
cheers
