[comp.sys.ibm.pc] NI5010 Ethernet Problem

dpm@cs.cmu.edu (David Maynard) (12/10/89)

I am using a Micom-Interlan NI5010 Ethernet board with both PC-NFS and
FTP Software's TCP/IP package (not at the same time) in a 12Mhz Packard
Bell AT clone.

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
