How to emulate arrow keys

[Robert Butera]

Hi,

I'm using expectit to automate a interaction with  console based application I access over ssh.

Am having trouble figuring out how to send the control characters required to emulate a user pressing the arrow key.

Any guidance would be much appreciated.

Regards

Rob

Hi,

What have you tried so far?  Perhaps expect.writeBytes({ 27, '[', 'A’ }) for arrow up will work

Thanks that worked.

Was using send() instead of sendBytes()

Hey Alexey,

On the same note I can get the arrow keys to send using:
[(byte) 0x1b, (byte) 0x4f, (byte) 0x42]; //^[[B

I'm having trouble sending the function keys though:

F5 comes up in my terminal as ^[[15~

This page suggests a lowercase 't'
http://www.programcreek.com/java-api-examples/index.php?source_dir=jopenray-master/src/main/java/com/jcraft/jcterm/EmulatorVT100.java

I've tried
[(byte)0x1b, (byte)0x4f, (byte)0x0F, (byte)0x7E] (the last two bytes are 15 and ~)
and
[(byte)0x1b, (byte)0x4f, (byte)'t']

Any suggestions on how to send the F5 key?

Thanks,
James

BTW we figured this out.
[(byte)0x1b, (byte)0x5b, (byte)0x31, (byte)0x35, (byte)0x7e]

The second byte was incorrect. I was using 'O' instead of '['

Hi, 

I'm trying to do a similar thing but for the numbers : 1,2,3...9.

I don't want to write the number but to simulate the numeric keypad.

In your response above, I didn't understand why there is a '[' and a 'A' :( 

Can you help me please ? :)

Best regards,

Alex CAMLAY
