AFor example, the Olympus IX-81 requires a login command from the  user (2LOG IN) followed by rn as an end of line. The  response will be 2LOG + followed by r. So a login command  would look like   p = do string "2LOG +\r"  return True  , login mgr = wrapCommand "\r\n" "2LOG IN" p  uses parsers that return  so users can choose D whether or not to match any given command based upon its contents, B rather than just blindly saying whether it matches or not.
