I have a Dell Latitude 5420. I purchased a USB to Serial interface to communicate thru serial port with MXP devices. I need to FLASH the memory of one of my units. The standard procedure is to do a BREAK command during boot up and type command eee in order to flash the memory. Unfortunatly, all these new keyboards don't have the BREAK function key available. Any ideas on how I can get my issue resolved?
I tried that and it doesn't work. The issue is that it is not only a BREAK command that needs to be sent, it's a CTRL + BREAK command. I've tried it with Hyper-Terminal, Putty, TeraTerm with the same result. Also tried different ways of typing it in (CTRL + B, ALT + B, etc.) with the same result. By looking on the web, the issue seems to be more related to the fact that Windows 7 doesn't support the BREAK key. Therefore, even if I try to simulate it with commands in Putty or Hyper-Terminal, I can't seem to be able to do the CTRL + BREAK. Can anybody try to simulate it with their laptop and confirm if they were able to get thru? I sure can't....
Tried that already but I think it's Windows 7 that doesn't understand the BREAK key itself. I was given a work around from CISCO to at least be able to access system commands thru telnet once the unit is booted up. It doesn't help me with my issue when an MXP system is stuck in a reboot loop, but, it does allow me to select software image or switch the units from PAL to NTSC (Cisco sends all the MXP replacements as PAL) which is normally done thru the system commands you can access once you do the CTRL + BREAK.
