+Slow the terminal to the old rates with a pipe and perl:
+
+```sh
+ff=/tmp/bashpipe
+mkfifo $ff
+( cat $ff | perl -We 'use Time::HiRes;$|++;while(read(STDIN,$c,1)){Time::HiRes::usleep(15000);print $c;}' ) & exec &> $ff
+
+```
+
+- Try running `dir` and `dir -F`!
+- Don't run interactive commands like `vim` or `top`!
+
+You can make it into a bash function by putting this into your `~/.bashrc`:
+
+
+```bash
+slow () 
+{ 
+    unset VISUAL;
+    EDITOR=ed;
+    alias ls='dir -F';
+    export PS1='[$?] \W $ ';
+    ff=/tmp/bashpipe_$(date +%s);
+    mkfifo $ff 2> /dev/null;
+    ( cat $ff | perl -We 'use Time::HiRes;$|++;while(read(STDIN,$c,1)){Time::HiRes::usleep(15000);print $c;}' ) & exec &> $ff;
+}
+```
+
+Then type:
+
+```bash
+exec bash
+slow
+```
