RE: [misterhouse-users] What causes CRC errors?

[Cyber L. <cl...@xg...>]

I may try that. I am suspecting that it is rf interference in the cable.  
The cable is unshielded and there is quite a bit of equipment in the
closet. I have some shielded cable I figured Id move the unshielded stuff
away from the computer systems. Ill also give the delay a try..
