NAME

     sab, sabtty -- Infineon 82532 Enhanced Serial Communication Controller
     (ESCC2)


SYNOPSIS

     sab*    at ebus?
     sabtty* at sab? channel ?


DESCRIPTION

     The sab driver provides TTY support for the Infineon (previously Siemens)
     82532 serial communications interface found in many Sun Ultra worksta-
     tions and servers.

     Input and output speeds for each line may be set to any baud rate in the
     following list: 50, 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400,
     4800, 9600, 19200, 38400, 57600, 76800, 115200, 153600, 230400, 307200,
     460800, 614400, 921600.


NOTES

     The speed cannot be changed on the ports connected the Remote System
     Control (RSC) on a Sun Enterprise[tm] 250 Server (ttyh2 and ttyh3).
     These ports are fixed at 115200 baud.


FILES

     /dev/ttyh[0123]
                  serial ports


DIAGNOSTICS

     sab*: ring overflow
             The software input "ring" has overflowed.  This usually means
             input flow-control is not configured correctly (i.e. incorrect
             cable wiring).


SEE ALSO

     tty(4), zstty(4)


HISTORY

     The sabtty driver first appeared in OpenBSD 3.1 and was then ported to
     NetBSD 2.0.
