Text telephone (TTY) mode is used for text communication over a telephone line. A TTY device must be connected to the computer to interpret the modified audio; otherwise you might experience poor audio quality during the call. Using TTY mode in a conference call might also cause audio quality issues. By default, TTY mode is turned off. You can turn on TTY mode by clicking Phones in the Lync - Options dialog box. You will then need to sign out of Lync 2010 and sign back in to use the feature.
I see that ttyS0 has the console [ttyS0] enabled associated with it where the ttyS1 does not. I was wondering what the console [ttyS0] enabled means? I think this is because of unix history. Originally, as this is well explained in that mail, there was two kind of serial port: the /dev/tty* and the /dev/cu*. Long story short, the tty ones are for incoming connections over the serial port, and the cu ones are for outgoing connections over the serial ports.
