baseconfig.txt lives in your Images directory by default (Look closely at the graphic above you will see that in that case it was D:\GNS3-Common\Images\baseconfig.txt)
By default, your Images directory will be ~/GNS3/Images or %HOMEPATH%\GNS3\Images
Although, as nickbeee says, each image can have a different file - it doesn't HAVE to be called baseconfig.txt (EXCEPTION - the Switch-router base config MUST be called baseconfig-sw.txt and MUST live in the Images directory and MUST be suitable for a c3725)
Also, by default, your baseconfig.txt WILL have the commands you want
line console 0
exec-timeout 0
(See nickbee's example)
Your problem is that you need to go to each machine and Press ENTER on each router to drop the CPU. That has nothing to do with the config. To do that, you have to make your terminal application send a
RETURN character or two as it starts up. Must work has been done on this by tranzitwww (
topic4859.html ) by writing scripts that are used to invoke the console application and send some chr(13)s to it, but nothing has been written for xshell 4. (I'm sure if you worked out exactly how to do it for xshell 4, and posted it back as a HOWTO on this forum other users would appreciate it )
I suggest you experiment with say SuperPutty or even TeraTerm to start with to see how he's managed to achieve teh CR send sequence in those apps, then adapte it to xterm 4
