- I bought a Supra 28.8 Faxmodem with Flash ROM and it appears to have a
- problem with noisey lines. The Flash died on mine and I had to send it
- back to have the flash replaced after only two months. I turned it off
- during a flash upgrade( a power loss during flash upgrade is leathal).
- I'm not sure it's worth it.
