PDF on AS/400

We are at V5R2 and are playing with converting spool files to PDF and then
e-mailing them.  I read the documentation in the Info center and actually
got it to work.  But now we have a small problem.  The documentation says
that you use the CRTDEVPRT command and create a *LAN type device using the
IP address 127.0.0.1 with a PSGCFG object which can contain an exit program
to like page group control values(from the STRPAGGRP keyword) to actual
e-mail addresses.  The problem is we want to be able to create multiple
devices with unique PSGCFG objects but only one of them can be active at a
time using the 127.0.0.1 address and if we use a different address the
device will not start.
