.Sh DESCRIPTION
The PC-Weasel is a serial console board for use primarily on
-Intel-based PC-class systems. It addresses a problem that
-nearly everyone who has deployed a PC-class server has experienced:
-the total lack of remote management capability on PC-class hardware.

In addition to serial console support, the PC-Weasel provides the
ability to remotely reset the system (by means of a hardware reset
signal), and provides a watchdog timer function.

The PC-Weasel works by emulating the original IBM Monochrome
-Display Adapter (MDA). Writes to the display's character
-cells are translated into ANSI terminal sequences which are
-then sent out the PC-Weasel's serial port. Incoming characters
-are translated into PC keyboard scan codes and then fed (by means
-of a cable) into the system's keyboard controller. The system
-believes it is using a display console. This is particularly
-important in the event that one needs access to BIOS configuration
-menus.

The PC-Weasel also includes a ST16550 serial port, which may
-be configured as any one of the system's serial ports. Typical

-at ISA I/O address 0x3f8. When the PC-Weasel detects activity
-on the ST16550, the serial port is automatically connected to
-the ST16550 so that the serial port may be used as normal. When
-the PC-Weasel detects activity on the internal UART used for MDA
-emulation, the serial port is automatically reconnected to the
-emulation UART. This allows the boot program and kernel to be
-configured to use the serial port directly (which is more efficient
-than using the MDA emulation mode), yet allows the MDA emulation
-to be reestablished as soon as the kernel loses control of the
-system.
