and <cr>. For example, if using the default port select code, send
$BTI<cr>. If a workstation issues this command and another
workstation is currently receiving immediate mode data, the
requesting workstation will receive the message "Immediate Mode in
use".
The V72 will send the message "Command/configuration mode in
use" to a workstation that attempts to access command mode of a
module while another workstation is currently in command mode for
that module. The requesting workstation will not be able to
place a module into command mode until the other workstation either
issues a disconnect command ($BT<cr>) or makes a connection to a
specific peripheral communications port.
4. A host connection to the V72 is terminated by sending the port select
code ($BT - default), capital "X", and <cr>. For example, if using the
default port select code, send $BTX<cr>.
NOTE: Some workstation TELNET client packages will not terminate their
side of the TCP connection when the server initiates an end to data
transmission, resulting in an unwanted half open TCP connection. To avoid
this situation, it is best to terminate a TELNET session from the workstation
if that capability is provided with the workstation TELNET package.
REVERSE TELNET OPERATION
The V72 provides a Telnet Client which is available if the M-Series unit has a V71
serial host module or V93 modem host module installed. This service is invoked by
connecting a terminal or PC running communications software to the V71 or by dialing
into a V93 and entering $BTn,p<cr>, where $BT is the default port select code
(assuming the default port select code is used), n is the module number of the V72, p is
the V72 client port number (which must be between 80-95n). The V72 will respond
with the following message:
V72 Host Telnet Client Service.
Enter target IP address in dotted decimal form:
Enter the IP address of the device to which you wish to connect as a series of four
decimal numbers separated by periods. There is no name resolver at this time, so the
user must know the IP address of the destination. When the address is correctly entered,
press "<cr>". A connection progress report will be displayed similar to the following:
