472 ---help---
473 If you like to use the MFP serial ports ("Modem1", "Serial1") under
474 Linux, say Y. The driver equally supports all kinds of MFP serial
475 ports and automatically detects whether Serial1 is available.
476
477 To compile this driver as a module, choose M here.
478
479 Note for Falcon users: You also have an MFP port, it's just not
480 wired to the outside... But you could use the port under Linux.

600 If you say Y here, it will be possible to use a serial port as the
601 system console (the system console is the device which receives all
602 kernel messages and warnings and which allows logins in single user
603 mode). This could be useful if some terminal or printer is connected
604 to that serial port.
605
606 Even if you say Y here, the currently visible virtual console
607 (/dev/tty0) will still be used as the system console by default, but
608 you can alter that using a kernel command line option such as
609 "console=ttyS1". (Try "man bootparam" or see the documentation of
610 your boot loader (lilo or loadlin) about how to pass options to the
611 kernel at boot time.)
612
613 If you don't have a VGA card installed and you say Y here, the
614 kernel will automatically use the first serial line, /dev/ttyS0, as
615 system console.
616
617 If unsure, say N.
