From: Huajie on 27 Jun 2008 10:14 Dear all: I need to save the screen output (Screen Shot) which updated continusly to a file in my Unix computer. I have a machine connects to my computer. When I plug in a sample in the machine, it automatically outputs data updated continuously to my computer through a series port and I don't need to type in any command. Can anyone kindly tell me how I can save the output to a file automatically so that I can read the output later? Thanks a lot in advance. Alex

[...] If you use GNU screen to connect to the serial port, you can use <Ctrl-A>H which will create a ~/screenlog.<x> file logging all the output. minicom also has a similar functionality. How are you /connecting/ to the serial port? -- St�phane

I am not using GNU screen. > How are you /connecting/ to the serial port? Someone did it for me so I don't know how. I just saw he used a series line through series 232 port. After I logged in, nothing appeared on my hyperterminal screen. Then after I put the sample in the machine which is connected to my computer, the output automatically appeared on the screen. I have heard the term of minicom. Can you tell me how I can do use that? or can you just tell me when I lookfor minicom help or tutorial, which command/part should I look for? Thanks. Alex.

[...] minicom and screen are alternatives to hyperterminal (though I suspect hyperterminal only runs on Microsoft Windows systems). AFAIK, hyperterminal also has support for storing all the output to a log file just look in the menus. -- St�phane

If the connection is not through minicom, can I still use minicom to save the screen? Because what I need is just to save the screen automatically. Sorry for my elementary questions. Alex |
