Install the PCI to serial port driver in ubuntu10.04 Environment

 

First, install the serial port tool setserial.

Command: sudo apt-Get
Install setserial
, Using setserial
Tool to view the serial port information,

$ Sudo setserial/dev/ttys0- /Dev/ttys0, Line 0, UART: Unknown, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 Closing_wait: 3000 Flags: Spd_normal skip_test $ Sudo setserial/dev/ttys3- /Dev/ttys3, Line 3, UART: 16550a, Port: 0xb800, IRQ: 18 Baud_base: 115200, close_delay: 50, divisor: 0 Closing_wait: 3000 Flags: Spd_normal

The main objective is to bring the serial port and
PCI

Differences between extended serial ports. The difference is that
UART:

Wei
Unknow

. However, if you detect this step

UART

Is
16550a

Instead
Unknow

To prove that your system has recognized the extended serial port and does not need to be further configured.

Subsequently, use
Lspci

View
PCI

Device status, command:
Lspci
-V

. Output:

That is, the serial controller, followed by device information, such

Control chip, the following is the serial port details, such

The address is
0xbc00

.

Finally, set the serial device file
,

Modify the following command line according to the actual situation.

$ Sudo setserial/dev/ttys2 Port 0xbc00 UART 16550a IRQ 17 baud_base 115200 $ Sudo setserial/dev/ttys3 Port 0xb800 UART 16550a IRQ 18 baud_base 115200
