[RTTY] MMTTY and ICO 756 PRO3

[Robert Chudek - K0RC]

It doesn't sound like you have a hardware PTT line for the radio. That 
would be a third connection from a LPT, Serial, or USB/Serial port into 
the PRO 3 ACC jack.

Apparently you were using software PTT. (PTT via radio command)

You need to set that up in MMTTY configuration. It is not enabled by 
default.
