NAME
     sab -- Infineon SAB82532 (ESCC2) serial communications driver

SYNOPSIS
     device sab

DESCRIPTION
     The sab is	a Infineon (formerly Siemens) SAB82532 (ESCC2) serial inter-
     face chip used in PCI-based UltraSPARC Sun	workstations.  The ESCC2 pro-
     vides two independent input/output	channels per instance.	These chips
     are normally used to provide RS-423 and RS232 serial ports	for general
     purpose use.

     The sab driver supports all of the	standard tty(4)	ioctl calls.  The sta-
     tus of the	DTR, RTS, CTS, and DCD signals can be queried with TIOCMGET
     command, but, due to limitations in the hardware, only the	DTR and	RTS
     signals can be modified with TIOCMSET, TIOCMBIC, and TIOCMBIS ioctl(2)
     commands.

FILES
     /dev/tty[a-b]  Serial ports.

SEE ALSO
     ioctl(2), intro(4), tty(4)

HISTORY
     The sab driver first appeared in FreeBSD 5.1.

BUGS
     The sab does not support cua minor	devices.
