Information.” The code indicates why the TN3270
emulation program has not been able to contact the
host control program.
The status may also appear as Enabled without a
communications check code for a few seconds before it
changes to SSCP.
SSCP
The session is activated and communicating with a
host control program.
NVT
The 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
The 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).
TN3270E
The session is communicating with the host TN3270
program using data messages in TN3270E format. This
format uses a 5-byte header, various data types, and
TELNET END-OF-RECORD (EOR).
TN3287
Session is communicating with the host TN3270
program using data messages in TN3287 format. This
format uses one zero-byte prefix for LU type 1 or LU
type 3 data and TELNET END-OF-RECORD (EOR).
Host_application_name
The TN3270 emulation program is communicating
with the named host application, but printing has not
yet started. This name is shown if it is available from
the BIND image exchanged during session activation.
If the BIND image is not available, either the value
TN3270 or TN3270E is shown.
Printing
The TN3270 emulation program is communicating
with a host application, and printing is in progress.
