There are known problems with the earlier inetds, and with Reflection 5.2 (which is what we are using, too), so you might want to eval the newest version. We have always been on MPE 55, so I cannot address 50, except to say that according to what I have read, inetd has changed substantially since its initial release in 50. WRQ strongly recommends connecting with NS/VT. If you really really want to use telnet, check out AICS's QCTerm, and see how that works for you. I just downloaded it recently, and am favorably impressed with it. When your session deactivates, does the Reflection title bar show the active title bar color, or the inactive title bar color? I have had oddities where one of the dozen things I am running while take Windows focus away from my current screen. Have you been able to see if the session hangs in the sense that everything stops, or does activity continue? You might want to give the following a try; it sustains a conversation of several exchanges between the client and the host. WRQ Tech support sent me a script to test with, which I have adapted to my tastes. Any poor design is my own. I connect via telnet, open this RCL, and run it. You will of course need to replace 'MPE:' with whatever your system prompt is, and change the counter to taste. Also, I hold for one second, because holding for just the prompt was consuming 20% of the CPU. Here is the text: let v1 = 0 :begin if v1 > 999 display " I just did this $1 times" goto stop else let v1 = v1 + 1 display "Iteration #$1 ^M^J" transmit "SHOWME^M^J" hold for "MPE:" transmit "SHOWTIME^M^J" hold 0:0:1 goto begin endif :stop stop
