TOPS-10 Monitor Calls Manual Volume 2 AA-K039D ... - Trailing-Edge

TSK. [CALLI 177]
o The monitor enters the link into the .TKSOK
state.
o
The monitor issues a device on-line interrupt
to the job if the job enabled this condition
using the PSI system.
3 .TKFEA
Enters the link into the active state. Before
issuing this function the link must be in the
.TKSID state. All other states cause an error
code (TKILS%) to be returned. When this code is
issued, the monitor reads the local NPD pointed to
by argl and the remote NPD pointed to by arg2. It
then sends a Connect ~nitiate request to the
node/task specified in the remote NPD. It puts
the link into the .TKSCC state and takes the skip
return. The link remains in the TKSCC state until
a Conneot Confirm or Disconnect function is
issued.
If a Connect Confirm is issued, the monitor
discards the remote NPD pointed to by arg2. It
builds a new remote NPD using the information in
the Connect Confirm message (so that it can be
read by a .TKFRS function). The link is placed in
the .TKSOK state and the controlling job is given
a device on-line interrupt (if the condition was
enabled using the PSI system).
4 .TKFEI
If a Disconnect function is issued, the monitor
discards both the local and remote NPD
specifications. It places the link into the
.TKSID (idle) state and gives the controlling job
a device off-line interrupt (if the job enabled
this condition using the PSI system).
Enters the link into the idle state. This
function is illegal for those tasks in .TKSDC or
.TKSCC states and is a no-op for those already in
the idle state (.TKSID). The monitor performs the
following for those links in .TKSCI and .TKSOK
states:
State
.TKSCI
.TKSOK
Function
Both NPDs are released. The link state
is set to .TKSID.
A Disconnect Initiate is sent. The link
state is set to .TKSDC.
When Disconnect Confirmed message is issued at a
later time, the monitor frees both NPDs, sets the
link state to .TKSID, and issues a "device
off-line" interrupt.
