Ahh, but sometimes external modems can cause more problems thatn internal ones if lighting strikes close enough to cause a current flow in the serial cable. A friend of mine took out the UART (?) in his Amiga every 6 months for 3 years because lightning kept causing a current flow in his serial line due to magnetics. We couldn't for the life of us figure out why for the longest time until he unwrapped the cable to lay out flat (the excess was wound into a coil) and he didn't have any problems since. Sometimes truth is stranger than fiction. :) Nate
