[HECnet] DECnet performance problems (on TOPS-10)

TOPS-10 and RSTS (and RT-11) echo the keystrokes as they occur, while RSX and VMS echo when the read occurs. Also, RSX, if I remember right, echoes <ret> as carriage return, and the line feed occurs at the start of the next input, while RSTS echoes <ret> as CRLF. I think TOPS-20 is like TOPS-10/RSTS, but it's handled differently in Rterm. The reason is that TOPS-20 does a lot with command completion, so its Rterm mode is essentially single character mode (what Telnet would call "raw"). RSTS/TOPS-10 mode gathers a whole line locally then sends that over (unless you're in a screen editor or other application that turns on character at a time mode -- which RSTS calls "ODT mode" because of the debugger that uses it). paul -----Original Message----- From: owner-hecnet at Update.UU.SE [mailto:owner-hecnet at Update.UU.SE] On Behalf Of Bob Armstrong Sent: Thursday, September 01, 2011 11:03 AM To: hecnet at Update.UU.SE Subject: RE: [HECnet] DECnet performance problems (on TOPS-10) but echoes TOPS-10 style (which is also RSTS style) not VMS/RSX style. Ok, I'll bite - what's the difference in echo style between TOPS10/RSTS and VMS/RSX? And which category does TOPS20 belong to? Bob
