I use DX-Telnet through a cable modem (Road Runner) and don't have any problem staying connected. I did earlier, do to the way it was connected to my laptop, but that's another issue. I have the clusters that I use, set up to be pinged every 10 minutes as a keep alive. And, it works like a charm.
To stop the "unwanted attempted connections from various unknown urls", I use a D-Link Cable/DSL Internet Gateway between the cable modem and the PC. 73 - Ted - W8TTS Larry Alkoff wrote: > > On Mon, 4 Nov 2002 21:05:25 -0800, STU wrote: > > > Is there anyone out there that has a hard time staying connected > > to TELNET. > > I have a high speed cable connection that works great for the > > Internet.
