The  following   routines  can  be   used  by  device   drivers  to  access
teletypewriter (tty) devices:

ccllrrqq()         Clear character queue
ggeettqq()         Get a char from a character queue
ppuuttqq()         Put a character onto a character queue
ttttcclloossee()      Close tty
ttttfflluusshh()      Flush a tty
tttthhuupp()        tty hangup
ttttiinn()         Pass character to tty input queue
ttttiinnpp()        See if tty queue has room for more input
ttttiiooccttll()      Perform tty I/O control
ttttooppeenn()       Open a tty
ttttoouutt()        Get next character from tty output queue
ttttoouuttpp()       See if tty output queue has data available
ttttrreeaadd()       Read from tty
ttttrreeaadd00()      Read from tty
ttttsseettggrrpp()     Set tty process group
ttttssiiggnnaall()     Send tty signal
ttttssttaarrtt()      Start tty output
