I'm sure I'm not the first. I have a DET1 Blah blah blah...2.54Y
Firmware.=
Let me get to the point. I can get into the edit mode of
the hex viewer=
. As I understand it, what i'm looking at is all user
mem and not ROM. B=
ut the ROM is flashable. And there are
instructions already in place to d=
o it. And you can enter your own
apps by hand in hex and run them in the =
yahoo! feature or wherever.
All I want to do in turn XTND off or at least=
change the strings to
something else the POP3 server wont puke on (-ERR).=
0C1D30 in the rom
is what I'm looking to change. 0C1C70, AND 0C1DB0 as w=
ell. 06bab0 has
a couple of strings but thats all they are for what I kno=
w. So
basically what I want to do is change XTND to something that wont
=
return -ERR on most POP3 servers, and I want to do it without flashing
the=
ROM externally. I am more than willing to enter hex for a few
hours to m=
ake it work. Maybe someone will write an editor for the rom
someday. Any=
idea's anyone?

The Rabbit cpu used in the mailstations have a
hardware flashmemory function that works through the
parallel port. I don't know how to access it through
the printer port, but someone on the list probably
does.

Why do you think it is a Rabbit cpu??? It does not even
come close to mat=

Rabbit chips that I am aware of. As far=
as I know,
it is not a Rabbit part.
In my personal opinion, it is a cu=

But there is a built-in reflash function, in *software*.
One =
of the things that my "mailbug" debugger does is
interface with this nativ=
e reflash capability
(via parallel port & laplink cable), allowing you to =
re-program the mailstations codeflash.
So far, the only thing *I* have fl=
ashed in any of my
mailstations is code that lets me boot up the remote
d=
ebugger. But it can be used to flash whatever you want.
Ferinstince, if so=
meone was inclined to write completely
new firmware, mailbug can flash it =
into a stock mailstation.
Or, if you just want to make some changes to ex=
isting
mailstation firmware, it can reflash with your modified
firmware.
=
I have been working (Ha!) on a new version of the boot code
(code that boo=
ts up the remote debug functions of mailbug)
that can be used without erasi=
ng the existing mailstation
code. (The native reflash erases most of the =
codeflash
*before* you get a chance to "back it up".)
This new version wi=
ll (when I get it working) let you load
and execute your own code over the =
laplink, without killing
the existing mailstation code. It also will let =
you save
to disk an intact image of your particular firmware version.
Afte=
r saving your firmware to a file on PC, you can edit it
with whatever tools=
you like, and then flash your new
version back to your mailstation.
If y=
ou are working with mailstation firmware 2.53yr or 2.54,
you can do this n=
ow, with the currently posted mailbug 0.0.3.
There are images of those tw=
o firmware versions in the group
download area. So, for those two, you do=
n't really need to
save your own images.
One catch, mailbug 0.0.3 will no=
t let you change the first
four pages of codeflash with the native reflash.=
If you
load the remote debug boot code, then you can flash anything
anyw=
here. Mailbug 0.0.4 will flash the whole codeflash
without needing to load=
the remote debugger.

Of the 2 that I have ( 1 120 and a 150 ) the 120 has a
rabbit chip in it. It is apparently a discontinued
part that was replaced by the 2000. The Rabbit 2000 is
functionally similar. both are based on a Z180
compatible core. I'll have to take a peek at theh
150's innards and see what it has.

I opened up my other one and it has the
same chip set. Several months ago I did find the
part number on a chip directory, which listed it
a rabbit semiconductor CPU as compatible. I think
the 3si176 is a chinese clone.

Can you get the details on both chips (and any
differences)? I have tried many times to get hardware
and programming specs from various mfr's, but they are
only willing to selling the chips.
