tty problem

Dear all,
when I do a remote shell command from a FUJITSU Unix to an HP-UX,
I always get this:

Code:
15:36:35 + rsh -l storto obs2  sh /users/obs/storto/MESO-NH/tmp_olive_map_00CC/job_prepex_70JY_C00CC_20041103_19 
Not a terminal
stty: : Erreur inconnue
stty: : Erreur inconnue
	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2	2

but no problem when I login on the remote machine and type the same command.
If I do a rsh ... "tty" I receive
Code:
not a tty

while a tty directly on the remote machine give:
Code:
/dev/ttyq5

while a rsh ... "stty":
Code:
stty: : Erreur inconnue

and directly on the remote machine :
Code:
speed 9600 baud; evenp hupcl
intr = ^C; erase = ^H; kill = ^U;
eol2 = ^@; swtch = ^@;
susp = ^Z; dsusp = ^Y;
werase = ^@; lnext = ^V;
-inpck -istrip icrnl -ixany ixoff onlcr
-iexten echo echoe echok
-echoctl -echoke

I tried loading profile files at the beginning of the rsh command,
and changing some option regarding stty, but it does not work and I'm not able to solve the problem, and it's important for the execution of a shell script
from a remote calculator.
Thank you in advance,

Andrea

Name
       rsh - remote shell

Syntax
       rsh host [-l username] [-n] command
       host [-l username] [-n] command

Description
       The  command  connects to the specified host, and executes the specified command.  The command copies its standard input to the remote com-
       mand, the standard output of the remote command to its standard output, and the standard error of the remote command to its standard error.
       Interrupt, quit and terminate signals are propagated to the remote command.  The command normally terminates when the remote command does.

       The  remote  username  used is the same as your local username, unless you specify a different remote name with the -l option.  This remote
       name must be equivalent, in the sense of to the originating account.  No provision is made for specifying a password with a command.

       If you omit command, then instead of executing a single command, you are logged in on the remote host using

       Shell metacharacters which are not quoted are interpreted on local machine, while quoted  metacharacters  are  interpreted  on  the  remote
       machine.  Thus the command

	  rsh otherhost cat remotefile >> localfile

       appends the remote file remotefile to the localfile localfile, while

	  rsh otherhost cat remotefile ">>" otherremotefile

       appends remotefile to otherremotefile.

       Host  names are given in the file Each host has one standard name (the first name given in the file), which is rather long and unambiguous,
       and optionally one or more nicknames.  The host names for local machines are also commands in the directory If you put  this  directory	in
       your search path then the can be omitted.

Options
       -l username	   Logs you in as the specified user, not as your user login name.

       -n		   Redirects all command input to

Restrictions
       The  command  is  confused by output generated by commands in a .cshrc file on the remote host.	In particular, `where are you?' and `stty:
       Can't assign requested address' are messages which can result if output is generated by the startup file.

       If you are using and put a in the background without redirecting its input away from the terminal, it blocks even if no reads are posted by
       the remote command.  If no input is desired you should redirect the input of to using the -n option.

       You cannot run an interactive command like Use

       Stop signals stop the local process only.

Files
       /etc/hosts
       /usr/hosts/*
