Formatting Screen on 3500yl, 12.27 Code

joehenderson — Mon, 19 Jan 2009 17:52:17 GMT

All,

I have a hp-j8693a-3500yl-48g-pwr, running 12.27.

I have noticed when i login or do a screen trace the screen get cuts in half.. I running a few telnet scripts with tcpdump. I get ALOT of formatting commands in the dump.. Is there a way to remove all formatting/paging from a HP telnet?

I have never had this issues from other vendors..

Notice the "[1;24r." With other vendors these formatting do -not- show up..

Any ideas?

I can offer you no clue for your specific problem, the only thing I noticed that you are running a relative old software image. The latest version for that product family is K.13.49.

If an update would in fact help you I do not know.. :)

Hi,

You may get better results if you use one of the following commands:

Change the terminal type permanent:

ProCurve Switch 3500yl-24G(config)#
console terminal none
CAUTION: This command will initiate a raw mode with all terminal escape sequences removed from the output and will take effect after saving configuration and reboot.

Change the terminal type for the session only:

ProCurve Switch 3500yl-24G(config)#
console local-terminal none
CAUTION: This command will initiate a raw mode with all terminal escape sequences removed from the output. To exit this mode, use the command "console local-terminal vt100".

Regards

Holger

Holger,

This is a good start, I gave you a few points..

The VT100 is what i was looking for, however
when i use ansi, the split screen is still present with the original formatting codes..

When i use none I lose bksp, arrow keys, all "shortcut" keys for inputting/editing the command line..

I wonder if there is a way to remove the formating (split screen) like terminal type "none" and keep the shortcut keys like "vt100"..

I don't think there is currently a way to disable the escape sequences and keep vt100. So basically you may instruct your script to login, excecute "console local-terminal none", excecute your commands you want to run, excecute "console local-terminal vt100" and exit.
