GT Power is a bulletin board system (BBS) and dial-up telecommunications/terminal application for MS-DOS.
The source code for GT Power was sold twice during the late 1990s, again in 2008 and is currently the property of Tom Watt.
When it is running under OS/2, GT Power can also be used as a telnet BBS host and terminal program via use of an OS/2 shareware virtual modem application called VMODEM.
As time passed, a host mode was written into the application which allowed the user to accept incoming data calls.
The source code and rights were sold to Tom Watt in June 2008 and he has resumed development of GT-Power.
For the first time since Paul stopped development, the source code has been made to compile the EXEs as they were last released in 1994.
GT Power also has the undocumented feature of telnet compatibility, in both BBS host and terminal mode, when used with a virtual modem software package called VMODEM under the OS/2, eComStation and ArcaOS operating systems.
Other third-party software includes: A third-party mail transfer program, called Mailrun, was developed which allows GT Power Network systems to transfer mail using the bi-directional HS/Link protocol.
In theory, the use of the bi-directional protocol (which sent and received files at the same time) will shorten the length of dial-up netmail calls, saving the sysop some long-distance phone charges.
With proper setup, Mailrun can co-exist with MDRIVer, allowing systems to use both programs to transfer mail.
Mailrun is freeware, but does require a free key code from the developer in order to connect with other systems.
At various times during the late 1980s/early 1990s, the Network included hundreds of nodes in the continental United States, Canada, Hawaii, China, Australia, New Zealand, Bermuda, the Caribbean and much of Europe.
Where netmail is usually system-to-system, person-to-person mail, echomail was intended to be read & possibly replied to by users on all GT Power Network BBS systems.
On the downside, a slight disruption in network routing could cause active echos to appear quite stale.
Nearly all of the remaining GT Power Network BBS systems have replaced their dial-up networking with forms of mail transfer that take advantage of the Internet, by using either e-mail file attachments or some form of automated ftp.
