Well, they're right: You don't have a terminal, and that badly-programmed proprietary app apparently demand one even in batch mode. You'll have to fake the presence of a terminal somehow.
From
here:
Quote:
in the book "Adv. Programming
in the Unix environment" second edition,
on page 694 a program pty is described (source code), with can be used
to connect a programm to a pty, i.e. fake a terminal to the command.
The chapter clearifys a lot of pty/tty miracles to me.
Unfortunately the relevant section isn't visible on Google Books...
Also, the
expect language may be capable of this.
As a long shot, 'export COLUMNS=132' might be sufficient, maybe.

PTY(4) BSD Kernel Interfaces Manual PTY(4)
NAME
pty -- BSD-style compatibility pseudo-terminal driver
SYNOPSIS
device pty
DESCRIPTION
The pty driver provides support for the traditional BSD naming scheme that was used for accessing pseudo-terminals. When the device
/dev/ptyXX is being opened, a new terminal shall be created with the pts(4) driver. A device node for this terminal shall be created, which
has the name /dev/ttyXX.
New code should not try to allocate pseudo-terminals using this interface. It is only provided for compatibility with older C libraries that
tried to open such devices when posix_openpt(2) was being called.
FILES
The BSD-style compatibility pseudo-terminal driver uses the following device names:
/dev/pty[l-sL-S][0-9a-v] Pseudo-terminal master devices.
/dev/tty[l-sL-S][0-9a-v] Pseudo-terminal slave devices.
DIAGNOSTICS
None.
SEE ALSO
posix_openpt(2), pts(4), tty(4)
HISTORY
A pseudo-terminal driver appeared in 4.2BSD.
BUGS
Unlike previous implementations, the master slave device nodes are destroyed when the PTY becomes unused. A call to stat(2) on a nonexistent
master device will already cause a new master device node to be created. The master device can only be destroyed by opening and closing it.
The pty driver cannot be unloaded, because it cannot determine if it is being used.
