What about
$ less yourlogfile

That said, I tried Ctrl-S here, and it paused the listing for me (Ctrl-Q 
resumes).

Please check that your CYGWIN environment variable has "tty" (note that this 
has to be set before Cygwin DLL is loaded, so you should probably initialize it 
in your user or system environment variables)

$ echo $CYGWIN
nodosfilewarning tty


Now the bad news: unfortunately, this does not seem to work in all cases, and I 
don't know why:

Example 1 - OK:
$ for ((x=0;x<100000;x=x+1)); do echo $x; done
==> Ctrl-S / Ctrl-Q work as expected

Example 2 - BAD:
$ wc -l verylonglogfile
310030 verylonglogfile
$ cat verylonglogfile
==> Ctrl-S stops the listing, but I was unable to resume the output

Note that if instead of using puttycyg I execute cat verylonglogfile in a 
"normal" Cygwin (i.e. Windows CMD), everything is working fine although the 
pause is slightly delayed, maybe due to buffered output.

It's also worth mentioning that the hung job show up as "waiting to output":

(Cheers to Google's clunky Google Apps migration which kept me from seeing 
responses here...)

I don't want to use a pager that I'll have to step through the output a page at 
a time.  I want the log output displayed on its own, all the time, and be able 
to pause the output from time to time to read or copy text.

CYGWIN wasn't set to anything, but setting it to "tty" didn't have any visible 
effect.

^S does work when I run a Cygwin binary, eg. find, but not in general (in my 
immediate case, adb logcat).
