If you have a selected area on the screen (like to do a Print Selection) and let it scroll off the top of the screen without un-selecting it, some time in the future a selected area of the same "shape" appears in the display. Since it is usually a long time in the future, I suspect some kind of wraparound, perhaps a 16-bit wraparound in the selected screen area cells. This might not be enough of a problem to even diagnose, much less fix... [ The memory is stored internally as a wrap-around. Too late to fix it in 2.3.

When running 2.3b versions, and word, I have had word crash on me outright, and have telnet tell me that it was out of memory for a new session (even though I only had 2 open and had room for four or more).

I believe this problem comes from a bug in the FTP transfer of versions 2.3b3,b4,b5,b6 and b7. You MUST upgrade to 2.3b8 (or b9 - coming soon).

You asked for some typical problems with the NCSA terminal emulator. The following are tested against 2.2 on the PC; your mileage may vary. In general, I think that there are LOTS of little bugs in the terminal emulator; when you fix these I'll report more. Most, as I've remarked, are not serious. For a more accurate emulator, see my version of the VTEM package recently posted as part of tooltool, or available for anonymous ftp from hogg.cc.uoregon.edu as pub/vtem.shar. Some typical bugs: 0/ embedded control characters in an escape sequence terminate the sequence instead of having an immediate effect. For example, ^[[10;^M20r should execute first the CR then the SET SCROLLING REGION. See the VT102 manual, page 63. 1/ autowrap mode is broken. If you receive ^[?7h^[[10;80fx^[[Ay you should display a y in column 80 with an x under it in column 80. Instead, you display x in column 80 and y in column 1. This is perhaps the most serious bug I've seen, and the one most likely to break display programs. In general, a character printed in col 80 sets a flag that says the NEXT character should be preceded by a wrap. However, any cursor motion clears the flag. Your implementation is to perform the wrap immediately, which is wrong. 2/ Lots of bugs with scrolling regions which may also break some programs. ^[[23;24r (2 line scrolling region at bottom) creates a 3-line scrolling region. ^[[5r should set the scrolling region to [5;24]. Instead, in NCSA Telnet it sets it to [4;24] and seems to get the emulator totally confused. My description of the behavior is not complete, but it is buggy in any case. ^[20;20r is illegal since TOP isn't less than BOTTOM. However, on a real VT102, it is ignored, while in NCSA Telnet it sets the scrolling region to [1,20] or somesuch. 3/ origin mode doesn't work at all. ^[[?6h seems to be a noop. 4/ RESTORE CURSOR i.e. ^[8 if no previous ^[7 has occured should home the cursor (and on most versions of the VT102 ROM restores character sets and attributes to a reasonable value). In NCSA it restores things to a random state, including a random cursor position.

It is not useful to bypass ftp signon if ftp signon will later be required to transfer files. If it knows (or can be made to know) that password checking is enabled, perhaps it would be a good idea to supress the -n option, so it just generates: ftp 123.45.67.89 The next step in the password stuff would be to distinguish between reading and writing. I think I would set my machine up so anybody could read the disk but only I could write it... -------------------------------------------------------------------- Date: 22 Jun 89 16:13:00 PST From: "John Mulhollen" Subject: RE: NCSA Telnet beta test crashes how can i get a version I can use on my pc?

But PLEASE, make it a command-line option so that I can still use it like I do now. I often have memory constraints, and one of the redeeming features of NCSA_Telnet is the fact that it is completely unloaded when exited. -David- Bitnet: david@wubios.wustl ^ Mr. David J.

Is anybody working on this >problem? > >Pieter >bowman@science.utah.edu tn3270 works fine under MultiFinder. However, as distributed, tn3270 does not have its memory size set large enough for a Mac II. This is because tn3270 requires memory for offscreen bitmaps, and the size of the bitmaps varies depending on the screen size and number of colors. In my experience, any problems running tn3270 under MultiFinder have resulted from the memory size being too small. To adjust the memory size, use "Get Info" from the "File" menu in Finder or MultiFinder. Set the Application Memory Size to a large number, for example 700K. Start tn3270, and select "About tn3270" under the apple menu. Then click on the "Storage Info." button. The dialog box which comes up will indicate how much storage is in use by bitmaps, and how much is available. The Application Memory Size should be adjusted so that the amount of available storage is at least 64K. The graphics bitmap will not be allocated when there is not enough memory for it, so the memory allocation can be reduced by the size of the graphics bitmap if it has been allocated, and you are certain you will not be using 3179 graphics during your terminal session.
