Why is my child not returning

Question

When I run this script on both ASAOS and IOS devices it find that they are different in the enable_mode function, and issues 'terminal pager 0' for ASAOS, and 'terminal length 0' for IOS.

Then in the main function I have a 'show run' command issued. This command is issued on the IOS device, but it seems to stop right after the 'terminal pager 0' command is issued on the ASA.

Is it safe to assume that the only output to the console (other then 'print') is the last successful string?

Here is what I get when I run the script

terminal pager 0

home-as <= name of the ASA minus the last letter for some reason

show run <= show run command issued on the IOS switch

Got it working. I was using a variable "QOUTMORE" under "enable_mode" and "if what_os == 2". This variable was set to 'q' in another module called with "from modules.cmds import *", but instead I used a 'q' and not the variable in my "enable_mode" function. Not sure why its working but it is.
