Configuring Async Ports 12-13
Disconnect Timer
is an inactivity timer that determines the length of time the port can go without trans-
mitting or receiving characters, as determined by the parameters Timeout if No Logi n,
Timeo ut if No Ca l l, and Timeout if No Data. (The actual timeout may be up to thirty
seconds after the number of minutes specified.)
Disconnect Duration
is the length of time the PAD will drop the modem signals after logout of the user
(whether caused by a timeout or user command). For a dial-in line, this should be set
to something greater than 0, to ensure that the line does not remain physically con-
nected after a timeout or logout. For a leased or directly connected line, Disconnect
Duration should be 0, to avoi d di s conne ctions .
Timeout if No Login
if Y, starts the discon nect time r the mom ent the user en ters l ogin stat e; e.g., when DSR
is asserted on the modem, or when a direct-connect user logs out. As long as the dis-
connect timer has not expired, the user can continue to attempt to log in. On a dial-in
line, if the timer has expired and Disconnect Duration is not 0, a physi c al discon nect
will be initiated. (The modem signals will be dropped.)
If the user logs out, the Disconnect Timer will be ignored, and the line will immediately
be disconnected.
This parameter should be N for a leased line; otherwise, the PAD banner and prompt
will periodically be output. (This is harmless, but unnecessary.)
This parameter is automatically disabled on a PVC connection.
Timeout if No Call
if set to Y, starts the disconnect timer as soon as the user logs in or a virtual circuit is
cleared, and the PAD is ready to receive commands from the user. The timer is reset
every time the port receives or transmits a call.
This parameter is automatically disabled on a PVC connection.
Timeout if No Data
if set to Y, starts the disconnect timer as s oon as a virtu al circu it is connec ted. T he tim er
is reset every time the port receives or transmits a character. If Y is specified and the
user has escaped from the data transfer state (by pressing [Ctrl] [P]), any data s e nt to
the port will not be output through the port.
When the disconnect timer expires, the software will check for any data waiting to be
output, as well as the state of the user. If there is data waiting and the user has escaped
from data transfer state, the user will be returned to data transfer state, and the dis-
connect will be canceled.
This parameter is automatically disabled on a PVC connection.
Disconnect i f Clear Recvd
determines whether the user will b e logged out if he receives a Clear Request from the
networ k . A l s o, i f D isconnect T imer and Disconnect Duration are set to values other than
0, the modem signals will be dropped when the user is logged out.
This parameter is automatically disabled on a PVC connection.
