記錄下序列槽調試指令

記錄下正在使用的序列槽調試指令，防止忘記啦！

1. 檢視序列槽狀态：

cat   /proc/tty/drive/serial  

[email protected]:~$ sudo cat /proc/tty/driver/serial

serinfo:1.0 driver revision:

0: uart:16550A port:000003F8 irq:4 tx:15120 rx:2392 CTS|DSR|CD

1: uart:16550A port:000002F8 irq:3 tx:0 rx:0 CTS|DSR|CD

2: uart:unknown port:000003E8 irq:4

3: uart:unknown port:000002E8 irq:3

4: uart:unknown port:00000000 irq:0

5: uart:unknown port:00000000 irq:0

6: uart:unknown port:00000000 irq:0

7: uart:unknown port:00000000 irq:0

8: uart:unknown port:00000000 irq:0

9: uart:unknown port:00000000 irq:0

10: uart:unknown port:00000000 irq:0

11: uart:unknown port:00000000 irq:0

12: uart:unknown port:00000000 irq:0

13: uart:unknown port:00000000 irq:0

2.每秒更新并高亮顯示序列槽狀态變化

watch  -n 1 -d  'cat   /proc/tty/drive/serial '
