Fried Modem

[Gregory Cortelyou]

This is slightly OT as it concerns a G3 iMac which happens to belong to 
my Mom. To be more specific, it's a Blueberry 350 iMac. There is great 
wisdom on this list and I need some help. Recently the telephone 
company that serves my mother's area had some sort of major surge run 
through the phone lines. It was reported in the news and she knew her 
home was affected because her cordless phone/answering machine started 
making noise right at the moment. Anyway, she cannot connect to the 
internet via her dialup ISP. She gets a message saying there is no 
dialtone. This is not true, because dialtone is all you get. I was 
there yesterday and tried everything I could think of in 10.2 and in OS 
9. If you set it to ignore the dialtone you get it to dial out but you 
hear strange tones, not the normal ones and it never connects. I 
believe her internal modem is "fried". Does anybody know if this is 
easy to replace in this model? Or what are the options for an external 
modem for a machine like hers. I appreciate any help give the OT 
nature. I do have a G4 FYI.
