	Unfortunatly that is not a possibility as my kernel goes to big to
fit in the limited ROM I have if I compile the TCP/IP support into the
kernel.

Perhaps you could run ppp on the serial line to get to TCP/IP protocol.
Then use telnet for the console access, ftp for the file transfer,
and normal TCP/IP for gdb server.

Just a thought,

This is the solution we recommend to our customers who debug over serial and
we've found it to be very successful (except for the pain of setting up ppp
but ymmv ;-)

remote debugging on one serial line

[Agust Karlsson]

I am developing an embedded linux system on a platform (AMD Elan SC400)
where I only have one serial line available for all communications with the
host.
I.e. I have to use the same line for console (minicom), file transfer (rzsz)
and remote gdb with gdbserver.
My question is: has anybody been successfull in doing that and if so how?

Best regards
Gusti
