Minicom

in the CentOS system Before you introduce the minicom software in detail, let everyone know about the CentOS system, and then introduce the minicom software in the CentOS system. I hope it will be useful to everyone. Because you want to use the serial port minicom configuration device, so consider using the serial port management software, windows is easier, and directly use the super terminal.

With CRT, linunx is a bit more troublesome. Before using redhat's enterprise version 4.0 used minicom software, also wrote a ppt to explain how to use, now use CentOS forgot how to use it, before A few days more urgent use of putty directly, this software can be used directly to select the serial port, but there is a problem, that is, can not be copied, it is more troublesome when encountering long strings, think about using minicom software, run “minicom&rdquo ; But there is an error message: [root@host temp]# minicom

minicom: WARNING: configuration file not found, using defaults

Device /dev/modem access failed: No such file or Directory.

Search from the Internet and find that you can use minicom-s. You can find it by man minicom software. -s is the meaning of configuration. The warning message is that there is no configuration file [root@hostcy temp]# minicom -s Minicom: WARNING: configuration file not found, using defaults

The following is the configuration process, the interface is as follows:

Filenames and paths

File trans Fer protocols

Serial port setup

Modem and dialing

Screen and keyboard

Save setup as dfl

Save setup as..

Exit

Exit from minicom software

After selecting Serial port setup, the serial port setup menu option will pop up, as follows:

A - Serial Device : /dev /ttyS1

B - Lockfile Location : /var/lock

C - Callin Program :

D - Callout Program :

E - Bps/Par /Bits : 38400 8N1

F - Hardware Flow Control : Yes

G - Software Flow Control : No

Change which setting?

Press A Change ttyS1 to ttyS0, because my laptop only has one serial port COM1, if you use other settings. Press E and select Bps/Par/Bits as 115200 8N1. I think the general development board should be set up like this. Then press F to change Yes to No and exit.

The result before exiting should be like this:

A - Serial Device : /dev/ttyS0

B - Lockfile Location : /var/lock

C - Callin Program :

D - Callout Program :

E - Bps/Par/Bits : 115200 8N1

F - Hardware Flow Control : No< Br>

G - Software Flow Control : No

Change which setting?

After exiting, select Save setup as dfl as the default read configuration file.

Exit from Minicom

Select Exit to exit the configuration interface and reach the serial port. When you run the minicom software directly, you can use it.
