If appropriate, add dialup entries to <filename>/etc/ttys</filename> by duplicating serial device (<literal>ttyd</literal>) entries and using <literal>ttyc</literal> in place of <literal>ttyd</literal>. For example:
Context English Portuguese (Brazil) State
The cathodes of the diodes are connected to a common point, together with a 1 kOhm pull-down resistor. It is essential to connect the resistor to ground to avoid floating of the IRQ line on the bus. Os cátodos dos diodos estão conectados a um ponto comum, junto com um resistor de 1 kOhm. É essencial conectar o resistor ao terra para evitar a flutuação da linha IRQ no barramento.
Now we are ready to configure a kernel. Staying with this example, we would configure: Agora estamos prontos para configurar um kernel. Ficando com este exemplo, nós configuraríamos:
# standard on-board COM1 port
device sio0 at isa? port "IO_COM1" flags 0x10
# patched-up multi-I/O extension board
options COM_MULTIPORT
device sio1 at isa? port "IO_COM2" flags 0x205
device sio2 at isa? port "IO_COM3" flags 0x205 irq 3
# standard on-board COM1 port
device sio0 at isa? port "IO_COM1" flags 0x10
# patched-up multi-I/O extension board
options COM_MULTIPORT
device sio1 at isa? port "IO_COM2" flags 0x205
device sio2 at isa? port "IO_COM3" flags 0x205 irq 3
Note that the <literal>flags</literal> setting for <filename>sio1</filename> and <filename>sio2</filename> is truly essential; refer to <citerefentry><refentrytitle>sio</refentrytitle><manvolnum>4</manvolnum></citerefentry> for details. (Generally, the <literal>2</literal> in the "flags" attribute refers to <filename>sio</filename>2 which holds the IRQ, and you surely want a <literal>5</literal> low nibble.) With kernel verbose mode turned on this should yield something similar to this: Note que a configuração das <literal>flags</literal> para <filename>sio1</filename> e <filename>sio2</filename> é realmente essencial; consulte <citerefentry><refentrytitle>sio</refentrytitle><manvolnum>4</manvolnum></citerefentry> para detalhes. (Geralmente, o <literal>2</literal> no atributo "flags" refere-se ao <filename>sio</filename>2 que contém o IRQ, e você certamente deseja um "nibble" abaixo de <literal>5</literal>. ) Com o modo verboso do kernel ativado, isso deve render algo semelhante a isto:
sio0: irq maps: 0x1 0x11 0x1 0x1
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A
sio1: irq maps: 0x1 0x9 0x1 0x1
sio1 at 0x2f8-0x2ff flags 0x205 on isa
sio1: type 16550A (multiport)
sio2: irq maps: 0x1 0x9 0x1 0x1
sio2 at 0x3e8-0x3ef irq 3 flags 0x205 on isa
sio2: type 16550A (multiport master)
sio0: irq maps: 0x1 0x11 0x1 0x1
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A
sio1: irq maps: 0x1 0x9 0x1 0x1
sio1 at 0x2f8-0x2ff flags 0x205 on isa
sio1: type 16550A (multiport)
sio2: irq maps: 0x1 0x9 0x1 0x1
sio2 at 0x3e8-0x3ef irq 3 flags 0x205 on isa
sio2: type 16550A (multiport master)
Though <filename>/sys/i386/isa/sio.c</filename> is somewhat cryptic with its use of the <quote>irq maps</quote> array above, the basic idea is that you observe <literal>0x1</literal> in the first, third, and fourth place. This means that the corresponding IRQ was set upon output and cleared after, which is just what we would expect. If your kernel does not display this behavior, most likely there is something wrong with your wiring. Embora o <filename>/sys/i386/isa/sio.c</filename> seja um pouco enigmático com o uso do array <quote>irq maps</quote> acima, a ideia básica é que você observe <literal>0x1</literal> no primeiro, terceiro e quarto lugar. Isso significa que o IRQ correspondente foi definido na saída e limpo depois, o que é exatamente o que esperaríamos. Se o seu kernel não exibir esse comportamento, provavelmente há algo errado com a sua fiação.

The Cyclades multiport cards are based on the <filename>cy</filename> driver instead of the usual <filename>sio</filename> driver used by other multiport cards. Configuration is a simple matter of: As placas multiseriais da Cyclades são baseadas no driver <filename>cy</filename> em vez do driver usual <filename>sio</filename> usado por outras placas multiseriais. Configuração é uma simples questão de:
Add the <filename>cy</filename> device to your kernel configuration (note that your irq and iomem settings may differ). Adicione o dispositivo <filename>cy</filename> à sua configuração do kernel (observe que suas configurações irq e iomem podem ser diferentes).
device cy0 at isa? irq 10 iomem 0xd4000 iosiz 0x2000 device cy0 at isa? irq 10 iomem 0xd4000 iosiz 0x2000

You can omit this part if you are running FreeBSD 5.X with <citerefentry vendor="current"><refentrytitle>devfs</refentrytitle><manvolnum>5</manvolnum></citerefentry>. Você pode omitir esta parte se você estiver executando o FreeBSD 5.X com <citerefentry vendor="current"><refentrytitle>devfs</refentrytitle><manvolnum>5</manvolnum></citerefentry>.
Make the device nodes by typing (the following example assumes an 8-port board)<_:footnote-1/>: Crie os device nodes digitando (o exemplo a seguir assume uma placa de 8 portas) <_:footnote-1/>:

If appropriate, add dialup entries to <filename>/etc/ttys</filename> by duplicating serial device (<literal>ttyd</literal>) entries and using <literal>ttyc</literal> in place of <literal>ttyd</literal>. For example: Se apropriado, adicione entradas de discagem ao <filename>/etc/ttys</filename> duplicando as entradas dos dispositivos seriais (<literal>ttyd</literal>) e usando <literal>ttyc</literal> no lugar de <literal>ttyd</literal>. Por exemplo:
ttyc0 "/usr/libexec/getty std.38400" unknown on insecure
ttyc1 "/usr/libexec/getty std.38400" unknown on insecure
ttyc2 "/usr/libexec/getty std.38400" unknown on insecure

The Specialix SI/XIO and SX multiport cards use the <filename>si</filename> driver. A single machine can have up to 4 host cards. The following host cards are supported: As placas multiportas Specialix SI/XIO e SX usam o driver <filename>si</filename>. Uma única máquina pode ter até 4 placas host. As seguintes placas host são suportadas:
ISA SI/XIO host card (2 versions) ISA SI/XIO host card (2 versions)
EISA SI/XIO host card EISA SI/XIO host card
PCI SI/XIO host card PCI SI/XIO host card
ISA SX host card ISA SX host card
PCI SX host card PCI SX host card
Although the SX and SI/XIO host cards look markedly different, their functionality are basically the same. The host cards do not use I/O locations, but instead require a 32K chunk of memory. The factory configuration for ISA cards places this at <literal>0xd0000-0xd7fff</literal>. They also require an IRQ. PCI cards will, of course, auto-configure themselves. Embora as placas host SX e SI/XIO pareçam marcadamente diferentes, sua funcionalidade é basicamente a mesma. Os cartões de host não usam locais de I/O, mas exigem um bloco de memória de 32K. A configuração de fábrica para cartões ISA coloca isso em <literal>0xd0000-0xd7fff</literal>. Elas também exigem um IRQ. As placas PCI, é claro, se configuram automaticamente.
You can attach up to 4 external modules to each host card. The external modules contain either 4 or 8 serial ports. They come in the following varieties: Você pode anexar até 4 módulos externos a cada placa de host. Os módulos externos contêm 4 ou 8 portas seriais. Eles vêm nas seguintes variedades:
SI 4 or 8 port modules. Up to 57600 bps on each port supported. Módulos de portas SI 4 ou 8. Até 57600 bps em cada porta suportada.
XIO 8 port modules. Up to 115200 bps on each port supported. One type of XIO module has 7 serial and 1 parallel port. Módulos de porta XIO 8. Até 115.200 bps em cada porta suportada. Um tipo de módulo XIO possui 7 portas seriais e 1 porta paralela.
SXDC 8 port modules. Up to 921600 bps on each port supported. Like XIO, a module is available with one parallel port as well. Módulos de porta SXDC 8. Até 921.600 bps em cada porta suportada. Tal como no XIO, um módulo está disponível com uma porta paralela também.
