Can't connect to remote Evaluator 7T

Hello,
I am trying to set up a practical work session about interruption
handling for undergradate students.
We are using for this work Arm Evaluator 7T boards connected to Intel
Linux boxes via a serial link.
The tools for writing programs and observing their execution are
arm-elf-gcc, arm-elf-as, arm-elf-gdb and other Gnu tools.
I did some first trials using the Angel monitor which comes installed on
each board. I used for this the target rdi provided with gdb.
Now I want to use RedBoot instead of Angel.
I uploaded redboot.UU onto the board and then verified (using a
communication program) that redboot was properly installed (see redboot
banner below).
But when I launch arm-elf-gdb and type the command 'target remote
/dev/ttyS0' then gdb fails to talk to redboot :
=================================================================
$ arm-elf-gdb
GNU gdb 5.2
...
This GDB was configured as "--host=i686-pc-linux-gnu --target=arm-elf".
(gdb) set remotebaud 38400
(gdb) target remote /dev/ttyS0
Remote debugging using /dev/ttyS0
Ignoring packet error, continuing...
Ignoring packet error, continuing...
Ignoring packet error, continuing...
Couldn't establish connection to remote target
Malformed response to offset query, timeout
=================================================================
Could it be that the serial line is not configured as required on the
gdb side ? (using ckermit I had to force parity to none...)
Thanks a lot in advance for any help.
Pierre
