SAB(4) BSD/sparc64 Kernel Interfaces Manual SAB(4) 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. BSD October 29, 2001 BSD
