sab is 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
