sabis an Infineon (formerly Siemens) SAB82532 (ESCC2) serial interface chip used in PCI-based UltraSPARC Sun workstations. The ESCC2 provides two independent input/output channels per instance. These chips are normally used to provide RS-423 and RS232 serial ports for general purpose use.
sab driver supports all of the
standard tty(4) ioctl calls. The status 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
sabdriver first appeared in OpenBSD 3.1.
sabdoes not support cua minor devices.
