Solve : com ports?

1.	Solve : com ports?
Answer» since lightning struck close by here the other DAY I have been unable to get on the internet on my desktop computer. the computer is saying that the 56k connector is working properly but I am not showing any com ports at all on the device manager list. anybody know what the problem is or how to correct it?56k Modem (dial-up modem) is dead. Lightning inducted power surge on the telephone line has killed it.This may be a good excuse to upgrade to DSL or cable modem service. If that's not an option, invest in a good UPS battery backup unit with a surge protector for the phone line. You should have a UPS unit anyway.how can the modem still be showing as working normally though?Quote from: dehner1cat on July 05, 2011, 01:59:27 PM ... the computer is saying that the 56k connector is working properly but I am not showing any com ports at all on the device manager list... Why don't you tell us EXACTLY what the computer says and what is not working. It could be the interface to the computer is working & the interface to the phone line is not working. The Device List should show a modem.Quote from: dehner1cat on July 05, 2011, 04:42:48 PM how can the modem still be showing as working normally though? Obvious if known what your computer is talking to and how surges do damage. First, surges rarely damage more than one part on a failed device. The modem's computer is rarely damage. Your motherboard computer is talking only to the modem's computer. Since the modem's computer is replying normally, then your motherboard computer (and OS) does not know a modem is damaged. Your failure is why better computer manufacturer provide COMPREHENSIVE hardware diagnostics for free. Talk to your modem using Hyperterminal to actually see error messages reported to and ignored by the OS (motherboard computer). A most common message for surge damage is "No DIALTONE Detected". A most common damaged part is a PNP transistor that drives the off-hook relay. Damage means both an incoming and outgoing path exist. Since all phone lines already have an earthed 'whole house' protector, then phone lines are rarely an incoming surge path. Phone lines are a best path to earth if a HOMEOWNER has let a surge go hunting inside the house. Most common incoming path is AC electric. Outgoing to earth via a phone line. A path that includes the PNP transistor. Energy is permitted inside if a home does not have a properly earthed 'whole house' protector on AC mains. Explained is why a failed modem is not reported (and why comprehensive hardware diagnostics are useful). What typically fails. And what must be properly earthed so that future damage does not occur.
