NAME
  iscc - serial communications interface

SYNOPSIS
  controller  iscc0  at	 isa0

DESCRIPTION
  An onboard Zilog 8530 DUART provides AXPvme-based Single Board Computers
  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 communications
  port.

  In the absence of a graphics head, the CON serial communications port
  (/dev/console) becomes the system console. When used as the serial system
  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 restriction.

  No modem control is supported for either the CON or AUX serial
  communications ports.
