had those too, that comes from the port opening

1st of all, i don't think that your phone understand AT commands at all...
my 3210 doesn't. instead there are two other protocolls: fbus and mbus
both protocols are binary. and to be able to talk to the phone i had to set
RTS to low! complely counter intuitive...
i have played around with fbus. i can send the sources to anyone
interested. i was able to read out the phone book and encoded (7bit
compressed or so) SMS, but it was some months ago. the sources are not
cleaned up but the low level part is usable.

i'd be interested too, if you hear something.

search for gnokii and you can have my sources for a start. the protocols
are not published, but the people at that project did some reverse
sorry for the late response, but i completely missed that thread, just saw
it in the weekly summary.
