Auto Coax Recovery
Auto Coax Recovery is a feature that will allow you to move a powered on display from one
coax connection to another without having to power cycle the display to bring it active again.
Enabling this option will cause LINCS to send a Reset poll to a device that has stopped
responding to the normal poll in such a way that the device appears to have been powered
down. When a device is connected to the port and receives a Reset poll, it should give a POR
response and come active through a normal exchange.
Resource Authorization Matrix
The Resource Authorization Matrix is used to give devices using this profile access to LINCS
resources. The individual resources are listed under the RESOURCE DEFINITION column.
The unprotected portion of the matrix is headed by column numbers 01-32. These numbers
represent something different depending upon the resource definition. Setting the value to 1
under a particular column allows devices assigned to the profile to have access to that subset
of the resource.
For example, there are 64 available classes for a 3270 Host, arranged in two rows of 32. A
device using this Display Profile will be able to access any host resource defined by the Host
Classes that are enabled. If no Host Classes are enabled for this profile, then the device will
not be able to connect or disconnect to any host resource.
Even if you have not allowed any access on the Resource Authorization Matrix, and no Dynamic
Access, you can still configure a device using this profile to preconnect to any host, host
class, or LU, on the Device Profile/Host Assignments panel. That method of granting host
access means that the display will connect to the LU when powered on, but cannot connect to
any other session.
Enabling DYNAMIC ACCESS allows devices using this profile to access resources beyond
those defined in the host classes. For example, if a device is given Dynamic Access to 3270
Hosts, then a session may connect to any 3270 LU, even if that LU is not defined in a host
class. Even if you enable no classes, Dynamic Access allows the user to connect to any LU
the user knows about, as long as it is not already in use by someone else.
3270 Host Class Access
The matrix columns represent the sixty-four 3270 Host Classes. Setting the value to 1 under
column X allows devices in the profile to have access to 3270 Class X.
Setting the value to 1 under the Dynamic Access column allows devices with this profile to
connect to a specific 3270 LU (i.e., Host and LU can be entered on the 3270 connect panel to
connect to a specific 3270 LU).
ASCII Host Class Access
The matrix columns represent the sixteen ASCII Host Classes. Setting the value to 1 under
column X allows devices in the profile to have access to ASCII Class X.
Setting the value to 1 under the Dynamic Access column allows devices in the profile to
connect to a specific ASCII Host (i.e., an ASCII host A0-D7 can be entered on the ASCII
connect panel to connect to a specific ASCII Host).
