# 透過 RS-232 操作 Linux console

Debian sample

修改 : /etc/lilo.conf

增加 2 行 serial=0,9600n8 vga = normal #

image= ... append="console=ttyS0"

改好之後重新執行 lilo

修改 : /etc/inittab

\#Example how to put a getty on a serial line (for a terminal)

\#T0 for ttyS0

T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100 #T1:23:respawn:/sbin/getty -L ttyS1 9600 vt100

or

/usr/doc/faq/howto/NET-2-HOWTO.gz 有講得很清楚.

1. /etc/inittab 在 # Serial lines 這段開一個 s2:45:respawn:/sbin/agetty -mt60 38400 ttyS1
2. /etc/rc.d/rc.S 最下一列開 /bin/sh /etc/rc.d/rc.serial
3. 如果您的 PC 沒有 multi-port of serial 的話, rc.serial 可以不要管了, 不過可以再去 check 一下, 我都是把 # Do AUTOMATIC\_IRQ probing 這段的 #AUTO\_IRQ=auto\_irq 關掉. 去 # MANUAL CONFIGURATION 把 ${SETSERIAL} /dev/cua0 uart 16550 port 0x3F8 irq 4 ${SETSERIAL} /dev/cua1 uart 16550 port 0x2F8 irq 3 打開
4. /etc/default 加一個 agetty.ttyS1

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://applezulab.netdpi.net/02-linux-xi-tong-cao-zuo/linux-console-over-rs232.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
