[comp.sys.ibm.pc.rt] Hardware Flow Control on 4 Port Ser

maher@uxh.cso.uiuc.edu (01/19/89)

  On a related topic, could someone indicate what the
  "pro" (protocol) abbreviations

      dtr
      cdstl
      dc

  stand for?  I assume 'dtr' means that the 'data terminal ready' line
  is used for flow control, but what about cdstl and dc?
