Simon Kueppers d22d8c0ef7 Added additional sample rates of 12000 Hz, 11025 Hz (with 90 ppm error) and 8000 Hz as required by some applications (such as SoundModem). 2023-02-21 13:02:13 +01:00
Simon Kueppers e85eb2f287 Changed PTT behaviour from RTS&-DTR to just DTR to enable use of certain applications. 
For unwanted assertion of the PTT (e.g. in CHIRP), an additional safeguard has been implemented that disables all PTT action whenever a character is sent to the radio. For a lengthy discussion see #11.
