, STS was capable of 2400 baud speeds (later hacks upped this to 14.4). Using internal software, one of these lines could be used to establish a link to another STS, effectively making the number of simultaneous users dependent on how many STS's were involved.

The interface and design was similar to DDial in that users logged into the system with a three digit number that served as a username. Once logged in, the user could change his name to whatever he wished, while his user number served as his identifier. Each user was assigned a user level. 0 was for non-members. Callers without a user number could log in for only a limited time. Usually 10 minutes, but this could be decreased to 5 when call volume was high. The numbered levels were for registered users, usually paying members. The upper levels, 50-99 were for various levels of moderators. The sysop

), making links to other STS's, creating channels or terrorizing lower-level users.

Commands

Due to how the system worked, all input was done on a single string of text, limited to 255 bytes (255 characters). All system commands were preceded by a slash, followed by the command, followed by any variables. For instance, to send an email to user #130, your command might be:

/e130 We meeting at the diner tonight?

The recipient would read his mail by simply entering:

/e

To send a private message to another user, the command would be:

/p130 Whats Up?

Because of its simple design, STS was thought to be unhackable. Successful attempts have been made in crashing an STS using line flooding (only for it to reboot), but there are no known successful attempts at hacking one without directly accessing the main console.

Versions

One STS did not require a hack to get faster speeds. Version 2.0 of the software supported up to 28.8k directly. V1.5 and later also had a far superior network linking mode to that of Diversi-Dial that supported encrypted data communications and would use IRC as a "hub" to link multiple systems without tying up more than one phone line per station. The software was produced by a company in Florida calling themselves "Lightspeed " and STS-01 was called Fantasia, the successor to a D-Dial of the same name. The system was run by Falkor and the software was designed by him as well as his CoSysOps Creidiki, Troubador and Trillian.
