  Unspecified modem communications hang? 
 The Question is:
 
A modem connected to a com port hangs and we need to stop and restart the port
 What is the syntex for doing this?
 
Thank you.
 
 The Answer is:
 
  Without details on why the port is hanging and how the port is
  configured, no specific answer is available -- there are various
  discussions of correctly setting up a modem here in Ask The Wizard.
 
  If this is a case of flow control, you can try to clear it using
  SHARE privilege and the SET TERMINAL/XON command.  Alternatively,
  replace the modem with a terminal and try to use that to clear
  the port.
