Originally I asked if it was possible to use the Telnet client on the HP3000 to
connect to an AS/400 using either
HP2392 or HP700/92 terminals.  I'd like to thank Ross and Jeff for putting me
on the right track.  I used Jeff's escape
sequences from his Basic program to create a command file that sets up the
terminal to accept ANSI codes.  I haven't
tried it with an HP2392 terminal, but the HP700/92 seems to work fine.
