Establishing Telnet connections to ATS is much the same as establishing Telnet connections to a normal UNIX or LINUX Telnet server. Just configure your Telnet client to point to the server’s IP address and designated port # (default 23 unless changed by the –p command line parameter to ATSD.EXE), and then make the connection. The main difference is that instead of getting an operating system login prompt, you will be taken directly into A-Shell.
If you care at all about security, then it behooves you to implement a login mechanism within A-Shell itself, since with ATS, there is no operating system login. Note that since you can retrieve the IP address of the workstation using XCALL CONDEV,IP$, you could also implement your own simple firewall by forcing any connection from a non-authorized IP address to immediately exit.
