[GreenKeys] MMTY running a Model 28 ASR

[Jim Haynes]

If you run MMTTY on a computer that has a COM port and you tell it to use
that COM port for PTT and FSK, it will send RS-232 Baudot out the COM
port.  Then you need to make a RS-232 to current loop converter to
drive the TTY from the program.

This only works for sending from the computer keyboard.  It does not work
for receiving off-the-air.
