35 I don't recall what the defaults are, maybe it would help if you changed the
36 parameter for your kernel to console=ttyS1,115200n8r or whatever suits your
37 config.
38
39 As for the kernel, everything you need should be in
40 Device Drivers -> Character devices -> Serial drivers
41
42 My config:
43
44 <*> 8250/16550 and compatible serial support
45 [*] Console on 8250/16550 and compatible serial port
46 [ ] 8250/16550 device discovery via ACPI namespace
47 (4) Maximum number of non-legacy 8250/16550 serial ports
48 [*] Extended 8250/16550 serial driver options
49 [*] Support more than 4 legacy serial ports
50 [*] Support for sharing serial interrupts
51 [ ] Autodetect IRQ on standard ports (unsafe)
52 [*] Support special multiport boards
53 [*] Support RSA serial ports
