Can we see exactly what the program produces? The "sed" is to make all characters visible

Code:
var="$(/disk/sio -p3 -b57600 -R)"
echo "$var" | sed -n l

By the way, what Operating System and version do you have? This should dictate what type of Shell is /bin/sh .

I actually think that $var is empty, but I don't the same Shell as you in order to generate the exact error message.

smrsh

smrsh(1M)						  System Administration Commands						 smrsh(1M)

NAME

       smrsh - restricted shell for sendmail

SYNOPSIS

       smrsh  -c command

DESCRIPTION

       The smrsh program is intended as a replacement for the sh command in the prog mailer in sendmail(1M) configuration files. The smrsh program
       sharply limits commands that can be run using the |program syntax of sendmail. This improves overall system security. smrsh limits the  set
       of programs that a programmer can execute, even if sendmail runs a program without going through an alias or forward file.

       Briefly,  smrsh limits programs to be in the directory /var/adm/sm.bin, allowing system administrators to choose the set of acceptable com-
       mands. It also rejects any commands with the characters: ,, <, >, |, ;, &, $, 
 (<RETURN>), or 
 (<NEWLINE>) on the command line to  pre-
       vent end run attacks.

       Initial	pathnames  on  programs  are stripped, so forwarding to /usr/ucb/vacation, /usr/bin/vacation, /home/server/mydir/bin/vacation, and
       vacation all actually forward to/var/adm/sm.bin/vacation.

       System administrators should be conservative about populating /var/adm/sm.bin. Reasonable additions are utilities such as  vacation(1)  and
       procmail.  Never  include  any  shell  or shell-like program (for example, perl) in the sm.bin directory. This does not restrict the use of
       shell or perl scrips in the sm.bin directory (using the #! syntax); it simply disallows the execution of arbitrary programs.

OPTIONS

       The following options are supported:

       -c command

	   Where command is a valid command, executes command.

FILES

       /var/adm/sm.bin	       directory for restricted programs
