As jumpy said, you would need to check the manufacturer's website for a firmware update.
I haven't used a 56k modem in the longest time, but with v.92 and software like NetWaiting, you can receive telephone calls on the same phone line, and choose to accept them while your internet connection is put on hold. Without v.92 the caller will either get a busy tone, or you will be disconnected from the internet if you choose to accept an incoming phonecall. Of course, your ISP has to support v.92 for all of this to work.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
