This appears to be bug in uemacs that's been known about for several
years.  The fix below is from the busybox mailing list 3 years ago
http://lists.busybox.net/pipermail/busybox/2009-February/068304.html:

  Or you could install this one:
  ftp://ftp.kernel.org/pub/software/editors/uemacs/em-4.0.15-lt.tar.bz2
  but beware that this version also has a problem with ^S/^Q because
  it doesn't clear IXON.  You'll need the following patch before ^S/^Q
  will work at all:

If I submitted a patch and a modified uemacs.mk would it likely be
accepted?
