The console/contty ports are directly serviced by the main CPU so they
should generally not be used for high speed work.

The console/contty and the cards with 4 serial/1 parallel port do not
support CTS handshaking.  The EPORTS cards with 8 serial ports does,
but it requires a special ioctl() to enable it so it may take some
effort to make it work with uucp.  Also, there are some problems with
the supplied drivers - call the hotline for the fixed version if you
are going to use eports.
