Hi Bill,
Open a socket to the device, send a command and read from the same
socket with a message, probably using lf, cr or crlf as line ending.
Never close the socket, unless you want to log out.
Below follows a very simple example, which may work only in theory but
which shows the basics of a telnet client.
// button script
on mouseUp
put "192.168.1.99:23" into myDevSock
set the cSock of fld "Command" to myDevSock
open socket myDevSock
write "hello" to socket myDevSock // whatever command is appropriate
read from socket myDevSock until cr with msg "gotReply"
end mouseUp
// card script
on gotReply theSock,theMsg
put theMsg into fld "Terminal"
select text of fld "Command"
end gotReply
// card script
on closeStackRequest
answer "Do you want to close the connection?" with "Yes" or "No"
if it is "Yes" then pass closeStackRequest
end closeStackRequest
// field "Command"
on returnInField
put the cSock of me into myDevSock
write the text of me to socket myDevSock
read from socket myDevSock until cr with msg "gotReply"
on returnInField
I haven't tested this, but it should work. You need a stack with a
field "Terminal", a field "Command" and a button. Put the scripts into
their respective places and change the IP and port numbers. If
necessary, change cr into crlf for example. You might need to escape
some characters before sending them to the telnet server; check the
documentation of the server.
You can find a complete, tested and working telnet *server* script at http://qurl.tk/9s

I want to script a session to a network device using telnet in Rev.
The goal is to log into a telnet device like a firewall and issue a
command. Are there any examples on how to do this?
I will want to log into a firewall via telnet in Rev with a name and
password in a session and issue a "reload" command on the device and
then respond to the confirmation Yes or No.
The idea is that I'll use the network and server monitor software
(Whistle Blower) to monitor the health of a firewall. If there is a
problem with the firewall Whistle Blower will open my compiled
application (to protect a login name and password) and it will issue
a command to reboot the target server.
