There are only a few command line options, but I'll entertain others....
Currently, the command line can take either:
1. A Path to a .tnt file, allowing full configurability but the .tnt file is binary not ascii
2. A single hostname, connecting automatically via telnet on the default port
3. A telnet url in the form
telnet://hostname

ort
If called from an embeded link in a web page, a URL of this form will cause whichever telnet client is defined as the 'default' telnet client to attempt the connection. AbsoluteTelnet prompts you to make it the default telnet client when you first run the program. If you accept, AbsoluteTelnet will handle telnet URLS when clicked from the browser. But, even if AbsoluteTelnet is not the default telnet client, you can still pass these URLs to it on the command line.
Will any of these work for you? Only method one supports connection via something other than telnet.
