BASE UNIT AND MODULE OPERATION
____________________________________________________________________________
114
Dots will be printed to the screen at the rate of 1 per second until the connection is
established, at which time the "Connected" message is displayed. Once the connection
is established, the target will take control of the session and the user may operate as
from any Telnet client. If the host does not respond or refuses the connection, the
following message will be displayed:
Cannot connect to host.
If a Telnet connection is terminated for any reason, the following message will be
displayed:
Host session terminated.
In both the preceding connection failure and termination cases, the user will be
prompted again to enter a target IP address.
To terminate a Reverse Telnet session, the user may log out of the server or issue a
disconnect command to the V71 or V93 (i.e., "$BT<cr>", if using the default port select
code). A logout from the server will cause the TCP connection to terminate, but the
client session will remain open and the user will be prompted for an IP address. Issuing
a V71/V93 disconnect ("$BT<cr>") will cause the client to issue a disconnect from the
server but no notice will be provided to the user as the V71/V93 - V72 connection will
have been terminated. Subsequent Telnet connections will need to be obtained by
opening another client session.
RESOURCE RELEASE FUNCTION
Circumstances may arise when it may be necessary to terminate a connection remotely
without having to reset the unit. For example, this situation will occur if a network user
does not terminate a port connection to a V74 port. Connection termination may be
accomplished using the Resource Release function. There are 3 specific methods to
accomplish a connection release. In addition, a fourth command can bed used to reset
the unit if necessary. These functions are described below (assuming the default select
code of "$BT" is used):
$BTRI<cr> Causes the Immediate Receive mode to be released.
$BTRC<cr> Causes the Command/Configuration mode to be released (except
if user is connected to the Service Port).
$BTRn,p<cr> Causes the module, port as specified by "n,p" to be released.
$BTRS<cr> Causes the unit to reset after first terminating all open sessions.
This may take several minutes, during which time the unit will not be
accessible .
