TN3270 Extensions for LUname and Printer Selection
Status of this Memo
This memo provides information for the Internet community. This memo
does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
Abstract
This document describes protocol extensions to TN3270. There are two
extensions outlined in this document. The first defines a way by
which a TN3270 client can request a specific device (LUname) from a
TN3270 server. The second extension specifies how a TN3270 printer
device can be requested by a TN3270 client and the manner in which
the 3270 printer status information can be sent to the TN3270 server.
Discussions and suggestions for improvements to these enhancements
should be sent to the TN3270E Working Group mailing list
. These extensions will be called TN3287 in this
document. This information is being provided to members of the
Internet community that want to support the 3287 data stream within
the TELNET protocol.
1. INTRODUCTION
The need to communicate with IBM mainframe systems has a number of
unique requirements associated with it. This document addresses
those needs in a TCP/IP communications network.
IBM terminals are generically referred to as 3270's which includes a
broad range of terminals and devices,not all of which actually begin
with the numbers 327x.
The 3270 family of terminals and the IBM mainframe applications
systems are VERY closely coupled and it is the nature of the way the
3270s and the applications interact which require that this document
be available to provide a consistent way for the TCP/IP environment
to interact effectively with the 3270 applications of the IBM
mainframe world.
