The options are of 526 the form "bbbbpnf", where "bbbb" is the baud rate, 527 "p" is parity ("n", "o", or "e"), "n" is number of 528 bits, and "f" is flow control ("r" for RTS or 529 omit it). Default is "9600n8". 530 531 See Documentation/serial-console.txt for more 532 information. See 533 Documentation/networking/netconsole.txt for an 534 alternative. 535 536 uart[8250],io,<addr>[,options] 537 uart[8250],mmio,<addr>[,options] 538 Start an early, polled-mode console on the 8250/16550 539 UART at the specified I/O port or MMIO address, 540 switching to the matching ttyS device later. The 541 options are the same as for ttyS, above. 542 543 If the device connected to the port is not a TTY but a braille 544 device, prepend "brl," before the device type, for instance 545 console=brl,ttyS0 546 For now, only VisioBraille is supported. 547 - http://vouters.dyndns.org:8080/ Philippe Vouters (Fontainebleau/France)
