Hi,
   I usually use my 486PC as dummy terminal and connect it to the work
   station at school via modem. I favorite editor is xemacs. These days,
   when I use xemacs in the situation above, control-s character is
   somehow  inserted. I never typed it. It means when I try to go a page
   down by C-v, the xemacs search for a string ^v. C-s character is
   generated randomnly. I don't know where it comes from. But, it has
   never happened before. Please let me know the details if you have had
   the similar experience. 
   Also, sometimes if I type C-s , it is interpreted as 'stop screen'
   command. I don't know why. Any type of feedback would be greatly
   appreciated. Thanks.

Your communication program must be using software flow control.  This uses
control-s and control-q to prevent overruns. The control-s says "stop while
I process the current input," and control-q means "ready to go again."
You should try to switch to hardware flow control (CTS & RTS).  That should
stop the inteference with emacs.

This is normal at the exec level.  You can use control-s to stop output
from passing by too fast to read it.  Use control-q to release the stop.
They are still marked on some keyboards as XOFF and XON.
