Configurar ttyS4 [Resolvido] [RESOLVIDO]

Edit.

Opa, editando aqui só para avisar que consegui achar a solução.
Por padrão, o Kernel somente aceita 4 dispositivos seriais, o que temos de fazer é
alterar esse parâmetro.

em /usr/src/linux/.config temos os seguintes itens

CONFIG_SERIAL_8250_NR_UARTS=4
CONFIG_SERIAL_8250_RUNTIME_UARTS=4

Alterei eles para 5 e funcionou normalmente.
Acredito ter como passar isso pelo grub pela que andei lendo,
só não cheguei a testar ainda.

Fica a dica para quem precisar.

Bom dia,

estou com uma dúvida/necessidade aqui.

Tenho uma máquina com 5 portas seriais, mas somente 4 estão funcionando.
gostaria de saber como configurar esta 5ª serial.
Abaixo estão as saidas de alguns comandos para mostrar como está o sistema aqui.
Obrigado.

setserial -g /dev/ttyS[0123]
/dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4
/dev/ttyS1, UART: 16550A, Port: 0xa000, IRQ: 16
/dev/ttyS2, UART: 16550A, Port: 0xa400, IRQ: 16
/dev/ttyS3, UART: 16550A, Port: 0xb800, IRQ: 18

setserial -g /dev/ttyS4
