Whydidmyapplicationworkwithaplug-in
interfacebuttimesoutwithaserialENET
interface?
Becausetheserialdeviceserverisanetworkdevice,itisdependenton
networkconditionsfortimelycommunications.Anunpredictabledelayis
associatedwithusingtheremoteserialports.Applicationsmayrequire
longerserialtimeoutstocompensateforthisdelay.However,different
applicationshandleserialtimeoutsdifferently,andeachmustbeadjusted
individuallytoaccountforyournetworkconditions.
