What is QWS3270 Mobile
QWS3270 Mobile is a TN3270E standards compliant emulation application that
allows mobile devices to connect to IBM mainframes over an existing TCP/IP
connection.
TN3270 is a widely used protocol for encapsulating 3270 data
streams in TCP sessions.

What are "Sessions"
The basic connection model used by QWS3270 Mobile is called a session. A
session is a named connection to a single host and associates all the attributes
and functionality that has been defined for connections with this host. This
allows you to have different options defined for different hosts or even have
multiple sessions to the same host with different options.
To define a
session, tap Menu > Connect > New.
Enter a name for your session and tap
OK. Specify
the host name or IP address for this host and
choose the correct port number.
Optionally you can specify an LU (Logical Unit)
name to use for this connection. You can now
use this or any other defined session without having to specify the
connection information again. Simply choose the session you want to
connect to from the list of defined sessions.

What are "Host Names"
The 'host name' is the name the host is known by TCP/IP (as distinguished from
the name you give this session).
This can
either be a name (such as "jollygiant.dnsalias.com" for our test server) or an
IP address (in the form of 70.51.81.169), as long as QWS3270 Mobile can resolve
the host address using network aliases and directories.
If you do not
know this name or address, you can obtain the host name from the network
administrator of the host to which you want to connect.Back to Top
Connecting to a Host
To connect to a host, use Menu > Connect.
If you already have a session defined, simply select it from the list and tap
OK. To define a new session, see
sessions.Back to Top
Disconnecting from a host
When you want to disconnect from a connected host, you can either
close the program (the connection will be closed automatically), or you can tap
Menu > Disconnect. This item is
disabled when you are not connected to a host.Back

Emulating 3270 Function Keys
Most Mobile device keyboards do not have the function keys F1 - F12
found on most PC keyboards.
You can emulate these keys by using the
following key combinations:
