I am currently using SecureCRT and while my vbs script works well on single routers once I try and use it on multiple concurrent sessions it fails. In particular the script fails to send the break signal when triggered and the routers continues to boot. I manually send the ctrl-break with the keyboard and it works instantly every time. I am using a Cisco router as an access server. I am using vbs scripts in SecureCRT on Cisco equipment to erase old configurations.

I welcome any suggestions.

crt.Screen.WaitForString "c2811 platform "
crt.Screen.Synchronous = True
crt.Screen.SendSpecial "MENU_SEND_BREAK"
crt.Screen.WaitForString "rommon 1 >"

These are the basic elements of the break at the beginning of the script.
