Break Key

E-mail Print

AbsoluteTelnet/SSH supports a number of flavors of 'break' depending on the type of connection in use.  AbsoluteTelnet can send breaks on serial ports and modems as well as in telnet and SSH2 sessions (sorry, no specification exists for sending breaks in SSH1 mode).   A break is always sent by hitting the ctrl-break key combination.

Serial Break:  AbsoluteTelnet sends a serial break when using a serial port or a modem.  The duration of the break signal is 1000ms.

Telnet Break:  When in a telnet connection, AbsoluteTelnet sends a telnet break in accordance with RFC854.  RFC854 does not include a mechanism for setting the break duration.

SSH2 Break: When in an ssh2 connection, AbsoluteTelnet sends a break in accordance with RFC4335.  SSH2 breaks allow the specification of the break duration.  The default duration for SSH2 breaks in AbsoluteTelnet is 500ms.

 

Break signals are sometimes required on the host side to access special menus or administrative functions.  Many times, it is interpreted as a command to terminate a program running on the remote host.  AbsoluteTelnet/SSH can send the break signals that are required for these functions, but the interpretation of the break and the action taken is completely host specific.

I've tried lots of different telnet/ssh clients, and I have two long-time favorites: Putty and Absolute Telnet. Putty, because it's such a quick download that on someone else's machine i can run it without going through an install, and it runs ssh. But for my own machine, the only choice is Absolute Telnet. It stores my password, terminal appearance and connection settings so that it's literally 2 seconds from clicking the icon to being logged in to my remote ssh accounts. It's incredibly customizeable, but not overwhelmingly so. I hardly ever pay for software (I'm embarassed to say), but I like Absolute Telnet so much I've paid for the full version and I'm glad I did. It's important to note that this software is maintained by one guy, Brian Pence, who personally answers people's questions on his online forum and answers email inquiries (he's answered a couple of mine, and always been really helpful). I gotta say, you hardly ever get this kind of commitment and personal touch in software anymore. --Ben Wheeler
