Controlling 3270 Emulation
Controlling Display Sessions
Status
Indicates whether the session is ready to communicate
with the host or is already communicating. To conduct
terminal emulation or to transfer files using the
session, you must enable it. To enable a session,
highlight it and choose <Change Status>. For more
information, see “Enabling and Disabling a Printer
Session”. The following list describes the possible
Status messages.
Disabled
Session is not communicating with TCP/IP. To conduct
terminal emulation or to transfer files using this
session, you must enable it by highlighting it and
choosing <Change Status>.
Enabled nnn
Session is initializing communications with
TCP/IP.The variable nnn is the communications check
code, displayed as -+z_nnn on the status line of the
3270 session. The code indicates why the TN3270
emulation program has not yet established
communications with the host. Appendix B, “Status
Line Information,” explains communications check
codes.
The status can also appear as Enabled without a
communications check code for a few seconds before it
changes to SSCP.
SSCP
Session has established communications with the host,
but is not yet communicating with a host application.
NVT
Session is communicating with the host TN3270
program using data messages in Network Virtual
Terminal (NVT) format. This format uses no header
and ends all ASCII lines with a carriage return and
line feed (CR LF).
TN3270
Session is communicating with the host TN3270
program using data messages in TN3270 format. This
format uses no header, LU type 2 data, and TELNET
END-OF-RECORD (EOR).
