Re: [ts-7000] Re: Problen with serial port on TS7260

[Ricardo Sifón <>]

OK Angel.

As I understood (from what I read in the manual), if only the jumper 2 is connected, you access the console by port ttyAM0, and if the jumpers 2 and 4 are connected, you access the console by port ttyAM1.

Am I correct?

 

And if I want to use the port ttyAM0 as a simple  RS232 port, I commented the line:

 

#lgn0:12345:respawn:/sbin/getty -L 115200 ttyAM0

 

on the inittab file.

 

But, the port doesn't work.

Is there any way to know if the port is working? Any particular command?

 

Best Regards,

 

Ricardo Sifón

Hola Ricardo,

While I am not as "blunt" as some on the list I do think that all of
your answers are in the manual.

JP2 is used in conjunction with JP4

ttyAM0 is a fully compliant RS232 port and ttyAM1 is not

The pinout on the ttyAM1 header is not standard

You mention that your app runs a a regular PC so it will work on the
7260.

I would use the cable that you are using and configure ttyAM1 as a
console and see that you can communicate with the 7260 over ttyAM1. If
that does not work suspect your cable. Suspect the cable strongly if
you did not make it yourself as per the manual

I would run the app on ttyAM1 and then port it to ttyAMO

Ricardo, the serial ports on the 7260 works and all the information you
need is in the manual.

I found this document invaluable after the first time I was flamed on a
list for asking a thoughtless question:

http://catb.org/esr/faqs/smart-questions.html#before

* Describe the symptoms of your problem or bug carefully and
clearly.

* Describe the environment in which it occurs (machine, OS,
application, whatever). Provide your vendor's distribution and
release level (e.g.: “Fedora Core 7”, “Slackware 9.1”, etc.).

* Describe the research you did to try and understand the problem
before you asked the question.

* Describe the diagnostic steps you took to try and pin down the
problem yourself before you asked the question.

* Describe any possibly relevant recent changes in your computer
or software configuration.

* If at all possible, provide a way to reproduce the problem in a
controlled environment.


All of us on this list want to help, that is why we are on it. None of
us on the list want to do your work for you.

All that said, this list has been invaluable to me more times that I can
count, mostly in the archives. I am always careful what I write to the
list because j.chitte might read it ;)

Saludos,

Angel

P.S. Please let us know when you solve it, many of use would like to
know. When you close the circle of questions and answers, those that
use the archives will know when to stop looking.
