3423.0. "LOOKING FOR QIO LAT FUNCTION !!!" by AUBER::LEVY () Tue Jan 28 1997 16:07

    
    Hello, I'm Catherine LEVY from TSC FRANCE
    
    
    One of my customer write an program to drive a DECserver 90M port.
    He use QIOs to the LTA port and must absolutely known when the 
    automate connected to the port, is offline (or when the DSR signal
    is lost).
    
    This can be seen with the DECserver command : SHO PORT n STATUS.
    
    Does any LAT function exists which can use to notify to the application
    that for example, the DSR signal is dropped ?
    
    Or is it possible to get in an program, the informations he see with
    the SHO PORT STATUS command ??
    
    Thanks for help.
    
    CATHERINE.

Not directly.  The LAT protocol doesn't provide for modem status to be
communicated to the host.  You can configure the DECserver with SIGNAL
CONTROL ENABLED on the port, such that when DSR is de-asserted the port is
logged out and the LAT session is torn down.  The host can certainly
detect this.  :-)
