Abstract

Disclosed is a method of integrating Telnet (*) server software into an incompatible application program to establish connections with requesting Telnet clients. This allows transmission of application specific data to and from the Telnet client using Telnet options. Data sent must be in a format suitable for the type of device assumed to be at the Telnet client end. The device determined during the Telnet options negotiation is usually a terminal like an IBM 3270, vt100 or IBM 3151 using Telnet protocol specifications. Interoperability of systems and applications are enhanced by hardware previously excluded. Value is added by protection of hardware investment, usability and increased function by multi-user access to single-user systems.

Applications for the TCP/IP Telnet Protocols

       Disclosed is a method of integrating Telnet (*) server
software into an incompatible application program to establish
connections with requesting Telnet clients.  This allows transmission
of application specific data to and from the Telnet client using
Telnet options.  Data sent must be in a format suitable for the type
of device assumed to be at the Telnet client end.  The device
determined during the Telnet options negotiation is usually a
terminal like an IBM 3270, vt100 or IBM 3151 using Telnet protocol
specifications.  Interoperability of systems and applications are
enhanced by hardware previously excluded.  Value is added by
protection of hardware investment, usability and increased function
by multi-user access to single-user systems.  This scheme allows the
use of 3270 devices with operating systems and applications which
previously could not support them.  Also, 3270 devices can be
geographically distant from the system on which the application is
running.  Additionally, it allows the possibility of multiple users
to work with applications that were considered single-user systems.

      Protocols described in the Telnet specifications assumes that
users have access to Telnet clients.  The features are:
 .   Provides 3270 device utilization for operating systems and
applications which were not designed to support 3270.
 .   Allows multi-user access to operating systems and applications
which were not designed to support that access.
 .   Allows remote access to applications over Local Area Networks
(LANs) or Wide Area Networks (WANs)..
 .   Protects investment in hardware and software for new
applications.

      Both the TCP/IP and Telnet suite of protocols are available in
the public domain and no restriction of implementation or use is
applied to them.  TCP/IP is a communications protocol created to
allow computer systems to communicate.  Telnet is a specification of
communication flows built on top of a communications protocol like
TCP/IP to facilitate remote terminal connection.  Implementations of
TCP/IP exist for IBM's range of operating systems including:
              OS/2* MVS  VM  AIX*  PC-DOS  OS/400*.
Telnet implementations exist for each of these TCP/IP products.  The
Telnet protocols...
