Difficulty Sending Character Stream Over Telnet Connenction

[Rich Chilausky <rchilausky@xxxxxxxxx>]

This is the scenario -

   Machine A - PC running Windows XP
   Machine B - AS/400 running OS v5r2

   The goal is to establish a telnet connection and log on from the
   Windows machine; execute an  application on the AS/400 and return
   the output to the Windows machine to be displayed via the emulator.

   Steps:
   1. Initiate a telnet session from Machine A using a VT100 telnet
   emulation+ program. A telnet connection is established with Machine
   B (port 23). The "negotiated" mode is VT100 full screen.   2. Log on
   over the telnet connection.
   3. Invoke an application program on Machine B from Machine A via the
   emulator+ . 
   4 .The application program on Machine B outputs a uniquely delimited
   character stream destined for the emulator+ on Machine A.
   5. The telnet server on Machine B inserts screen formatting
   character sequences into the stream.
   6. These unexpected sequences are not always handled by the
   emulator+ on Machine A. All "non-standard" sequences outside of the
   uniquely delimited character stream are discarded by emulator+ on
   Machine A; no so, when the sequences are inserted into the middle of
   the delimited sequence.

   What is the command/technique to stop the AS/400 telnet server from
   sending the formatting sequences to Machine A?  Is that the right
   solution?

Thanks for any help!

Cheers,
