Tandata Modem

Tandata Modems

The Tandata QL modems consisted of a three-stack set of devices.

Q-Connect

Q-Connect connects to the QL SER2 port allowing the computer to be used with virtually any asynchronous modem from 75 up to 9,600 baud, with full two-way buffering and flow control. Q-Connect was supplied with software on microdrive cartridge to support this and the other two modules. The software also supports both Prestel/videodata/videotext and VT100 emulation, as well as user-to-use communications.

Q-Mod

Q-Mod was a manual dial V23 modem operating at 1200/75 baud and 1200/1200 baud half duplex.

Q-Call

Q-Call provided traditional pulse/loop disconnect auto-dial and auto-answer.

Although the three modules were available separately, Tandata suggested that by using all three as a complete matched system full advantage could be taken of the integrated features of the Q-Connect's software.

The Tandata units were popular with QLers in the 1980s for use with the Prestel service and for Bulletin Board System connection.
