My solution is to run 'ping -i 60 HISADDR', where HISADDR is the IP address of the machine at the other end of the PPP link. The '-i 60' keeps the ping packets down to one a minute, so the overhead is insignificant. If the line is dropped, it is less than a minute before a redial is triggered by the ping packet. (Some day I'll get around to calling USR to ask about the system chip upgrade to fix the problem...) -Pat My opinions are my own. For a small royalty, they can be yours as well...
