[GreenKeys] HeavyMetal

[Duncan Brown]

Mike,

Basic description: Heavymetal takes text from the Internet (news, weather, stocks, email, etc), converts it to 5 level Baudot code (among others) and puts it out onto your COM port to drive your TTY.

Note that you need a real COM port on the computer.  Most USB-to-COM adaptors will not go SLOW enough for TTY.  

Unless you have a "low-level" (military) TTY, you will need a level converter to go from the COM port levels to normal TTY loop levels.  This can be easily done with an optocoupler like the HSR312. I built one inside the cover of the serial port 9-pin D connector.

Have fun,

Duncan
