Something else to think about on this subject. When using Locus' TCP, rebooting the PC with running clients is dangerous. The clients don't know that the PC (Server) rebooted and dropped their connections, so they keep right on talking to it. When the next incarnation of the server comes up, Locus' TCP hangs when one of these clients from the previous session sends data to it. Big problem, and no good way out of it. We've since switched to FTP's TCP, which properly sends a TCP-level reset back to any client (connection) it doesn't know about. The client goes away cleanly (perhaps only complaining about its connection being lost), and the server keeps running. >I have also tried to use GSS Software's PC-XView, but for some reason >I couldn't get it to work. We've also used GSS PC-Xview, but with better results. We're using a DGIS board and it's *lots* faster than the Super-VGA (Orchid ProDesigner Plus) server used on Locus' PC-Xsight. It does take a lot of fiddling to set up, though. The main problem with VGA servers (even the one on Interactive Unix) seems to be in bit-blt operations. For reasons I don't understand, they're very slow. Too slow for our customers. We've replaced the VGAs in Unix with 8514's, and in PC's with DGIS. -- Guy Finney It's that feeling of deja-vu UUCS inc.
