[olug] Trapping Strange Output

I'm trying to trap the output of the following command.

ssh -l user1 box1 -o BatchMode=yes ". /export/home/user1/.profile 2>&1 
1>/dev/null;. /home/superuser/fixer/sync.user1.env;/home/superuser/fixer 
78758000002063 002 X"

When I run the command by itself, outside of ssh, the results are as 
follows, which is exactly what I want:

user1 > . /export/home/user1/.profile 2>&1 1>/dev/null;. 
/home/superuser/fixer/sync.user1.env;/home/superuser/fixer/fixer 
78758000002063 002 X

But when I run it through ssh, it doesn't return any output. Here are the 
following variations that I've tried and each time I get nothing.

ssh -l user1 box1 -o BatchMode=yes ". /export/home/user1/.profile 2>&1 
1>/dev/null;. /home/superuser/fixer/sync.user1.env;/home/superuser/fixer 
78758000002063 002 X 2>&1"     # Trapping both STDERR and STDOUT

ssh -l user1 box1 -o BatchMode=yes ". /export/home/user1/.profile 2>&1 
1>/dev/null;. /home/superuser/fixer/sync.user1.env;/home/superuser/fixer 
78758000002063 002 X 2>/dev/null"     # Trapping STDOUT and dumping STDERR

ssh -l user1 box1 -o BatchMode=yes ". /export/home/user1/.profile 2>&1 
1>/dev/null;. /home/superuser/fixer/sync.user1.env;/home/superuser/fixer 
78758000002063 002 X 2>&1 1>/dev/null"      # Trapping STDERR and dumping 
STDOUT

ssh -l user1 box1 -o BatchMode=yes ". /export/home/user1/.profile 2>&1 
1>/dev/null;. /home/superuser/fixer/sync.user1.env;/home/superuser/fixer 
78758000002063 002 X 3>&1 1>&2 2>&3 3>&-"      # Exchanging STDERR and STDOUT

I'm at a loss. Any input would be very appreciated.

Thanks,
