Events
OnBufferOverrunChannel5/6/7/9
Description: One of these events will fire if a particular channel data buffer overflows. The
ActiveX control stores all data received from the Motion Coordinator in the
appropriate channel buffer when the connection has been opened in asynchro-
nous mode. As data is received it is the responsibility of the user application to
call the GetData() method whenever the OnReceiveChannelx event fires( or oth-
erwise to call the method periodically) to prevent a buffer overrun. Which event
is fired will depend upon which channel buffer overran.
