I've set exported TERM=vt100, called tset and stty and I keep observing artifacts.setting $TERM won't help with VMS :-) Now... you could use the xterm option to tell it (in effect) to tell the host not to send 8-bit controls: man xterm: -ti term_id Specify the name used by xterm to select the correct response to terminal ID queries. It also specifies the emulation level, used to determine the type of response to a DA control sequence. Valid values include vt52, vt100, vt101, vt102, vt220, and vt240 (the “vt” is optional). The default is “vt420”. The term_id argument specifies the terminal ID to use. (This is the same as the decTerminalID resource). That is, xterm -ti 100 or xterm -ti 102 and if the host is behaving properly, it'll give up on 8-bit controls. Of course, VT100's have no function keys (F1-F12), nor Home/End, PageUp/PageDown, but cursor-keys should work. Your experience here will depend on what the applications are using.This didn't help (starting "xterm -ti 100" on my NetBSD host and telneting to OpenVMS), however I have found the solution. I've set in OpenVMS the following option: SET TERMINAL/DEVICE_TYPE=vt100 py-terminator started to work correctly (and the same should happen with xterm). Thank you for your help!
The reason for this is that the VMS host will not magically know what kind of terminal you have. You need to (as you noted) tell it what terminal you have. Sometimes system managers put in a SET TERMINAL/INQUIRE into the system wide login script. That will make VMS try to detect what terminal you have, and could potentially have solved the problem if xterm have the right settings as well, but I suspect there is no SET TERM/INQ in there to start with, and then it is not enough to just fiddle around in xterm. VMS needs to know, just as Unix programs needs to know what terminal you have. In VMS you do it they way you noted above, and in Unix, you do it by setting the TERM variable.
