I have several 3750-48P running version c3750-ipservicesk9-mz.122-44.SE2 IOS and on some of the switches, when you telnet to them, and do a show config, the screen scrolls through the whole config without pausing. On other switches that are exactly the same, as far as I can tell, they pause after a page of information.
To set the number of lines on the current terminal screen for the current session, use the terminal length EXEC command.
<font size="2">terminal length <i>screen-length </i></font>
24 is the default
Hope that helps
