Don’t send Restore Kybd to TN3270 Client for NonSNA end-of-chain
Normally, LINCS restores the keyboard for TN3270 clients when a Non-SNA end-of-
chain is received, because many of them do not restore their own keyboards automatically.
This RPQ causes LINCS not to automatically restore the keyboard, forcing the client
emulator to restore it.
Don’t send Restore Kybd to TN3270 Client for NonSNA Deselect
Normally, LINCS restores the keyboard for TN3270 clients when a NonSNA Deselect
occurs, because many of them do not restore their own keyboards automatically. This
RPQ causes LINCS not to automatically restore the keyboard, forcing the client emulator
to restore it.
TN3270 clients MUST specify an LUNAME
Only clients that negotiate an LUNAME, are allowed to connect, and only if there is a
LINCS entry corresponding to that.
Allow a user to commandeer a 3270 session already in use
When a user connects into the SCON, and is given a connect panel to request a session
from, they have an additional option that allows them to take a session that is already
assigned and in use by another user, by specifically requesting the session and performing
the commandeer function. The person from which the session has been taken will be
given a connect panel from which they can take their session back if needed.
Assume all TN3270 clients support extended attributes
When enabled, LINCS will assume that the device supports Extended Attributes (such
as IBM 3278-2E device type) even if the client negotiates a device type that implies
that it does not support them (such as IBM 3278-2 device type). This is to accommodate
some emulators that negotiate that they do not support Extended Attributes, but they
really do.
Immediately Disconnect NonSNA Client
When enabled, LINCS sends to the host an Attention - Unit Check, when a client indicates
power down. Normally LINCS sends the Attention, and when the host attempts to select
the device, LINCS responds with Unit Check. This was required for some clients because
the console function does not roll soon enough.
Send TN3270 connection confirmation to device
When enabled, LINCS sends a NVT message to the client once they have successfully
negotiated a TN3270 session with us, to acknowledge success. Not all clients are capable
of displaying a NVT message once they have negotiated TN3270 options. In most
cases the host will almost immediately write to the device, so the message normally
