Cisco 5915 Serial Port Echo Problem

[embeddedman]

Hi everybody,

I'm working on a project that connects to Cisco 5915 over serial port from an application. I guess, router is echoing that everything I send. For example,

router> // router send

enable\r // I send

router>enable // router send and waiting for pressing enter again

\r // I send enter

router# // router send

However, when I use a serial terminal like picocom application, I don't see anything like this. Everything is good. For example,

router> // router send

enable // I write and press enter

router# // router send

When I look for settings for Cisco or picocom, I can not find anything. Also I work with picocom in raw mode.

Do you know anything about this situation ?

Thank you.

Hello,

can you post a screenshot of what that port echo looks like ?

Typically, the commands below would prevent the terminal/console from showing anything:

terminal length 0
terminal no monitor
no logging console

Thank you for your reply.

I can not catch a screenshot but I can write exactly it.

When I handle the first line, I send "enable\r". Then, router sends the second line. Actually, I'm waiting for just third line after send "enable\r".

router>
router>enable
router#

Hello,

--> When I handle the first line, I send "enable\r". Then, router sends the second line. Actually, I'm waiting for just third line after send "enable\r".

Not sure what you mean by 'handle the first line' and 'send "enable\r". What exactly are you typing, and what is the echo displayed on the screen ?

At the prompt:

router>

You type:

router>enable

What is the echo ?

Sorry about the confusion, a screenshot would really help...can't you use a smartphone ?

I'm coding an application and it is using serial port to communicate with cisco router. So, no any prompt and any screenshot.

Briefly, when I send "enable", it sends me "router>enable"
