iscc(7) Miscellaneous Information Manual iscc(7) NAME iscc - serial communications interface SYNOPSIS controller iscc0 at isa0 DESCRIPTION An onboard Zilog 8530 DUART provides AXPvme-based Single Board Comput- ers with console (CON) and auxiliary (AUX) serial communications ports. Both serial communications ports can operate at baud rates from B50 to B38400, excluding B134 (see tty(7)). On AXPvme Single Board Computers configured with a graphics head as the system console, the CON serial communications port (/dev/tty01) is available for use by application programs as an additional communica- tions port. In the absence of a graphics head, the CON serial communications port (/dev/console) becomes the system console. When used as the serial sys- tem console, the CON serial communications port always operates at 9600 BPS, 8-bits, and no parity. Regardless of system console, the AUX serial communications port (/dev/tty00) is always available for use by application programs. RESTRICTIONS Data communications equipment attached to the CON serial communications port must be set to 9600 BPS, 8-bits, no parity when configured as the serial system console. The iscc terminal driver enforces this restric- tion. No modem control is supported for either the CON or AUX serial communi- cations ports.
