Things work fine MOST of the time. Occasionally, however, telnet and ftp connections will hang in such a way that you have to hit RETURN (or somehow force another packet) to unjam the connection. I suspect that packets are being dropped somewhere and that the new packet forces a retransmission. Has anyone encountered a similar problem? The NI5010 is configured to use interrupt 5, DMA channel 1. Base address 300. I've considered turning OFF DMA (recommended for AT's by Micom-Interlan), but haven't opened up the case to do it yet. Could that be causing such a problem? Thanks for any suggestions, David --- David P.
