I'm having a spot of trouble getting vt100 2.9 to work right for me. What I need to do is be able to do ASCII capture/ASCII send. Now, I have several problems here: a) canyou set up the default to be ASCII? It seems to come up with Kermit as the default, but the XPROTO command doesn't list 'ASCII' as one of the available choices. b) The Menu list clains that A-^ and A-V are the send/receive controls, but I A-S and A-R are what seem to be compiled in. those two are just baby stuff... here's the real problem: c) I tried to upload a file. So I selected ASCII protocol, and then I selected SEND and it popped up a window and I typed in my file name. And nothing happened. So I ctrl-C'ed out of the script I use on my SUN to receive the ASCII uploads and *then* vt100 started sending the file, which, of course, caused a LOT of trouble as my shell tried to digest all of the stuff. So I tried again, this time without running my receive-script and I noticed two things: 1) it started sending right away [thereby not giving me a chance to type receive<cr> and pissing me off :-)], and 2) it didn't ask me for a file name. How *do* you start and stop an ASCII send? [as a side annoyance, somehow in the course of blundering around to try to turn OFF the ascii send so it'd ask me for a new filename, I managed to hit the CAPTURE menu item... well it didn't ask me for a filename either: it just used the same old filename... yup, trashing the file I was trying to upload...:-(]. Another littler question: how do you get a script to make vt100 go away. I have a little guy that does DELAHY 2 SEND "+++" DELAY 2 SEND "ATH^M" EXIT VT100 but that last doesn't really exit the program, but apparently goes and tries to find a script "vt100" to run... Thanks! /Bernie\

There is a long standing "problem" in vt100's ASCII send code--when you select ASCII send, it still waits for all the normal events that it usually waits for. The net result is that it doesn't start sending until it sees an event (I think a mouse click will do). With a full duplex connection, one event will do, since the echoed characters keep the stream going (but a few mouse clicks will speed it up). With a half-duplex connection, this is a real problem. My opinion is that vt100 should not wait at all in ASCII send--it should just dump the data straight over the line. I included a trivial change to do this in a *big* list of bug fixes I sent Tony after 2.8 came out, but I think my list must have been lost in the mail--none of my fixes appeared in vt100 2.9 (worst example: vt100 is still doing a Wait() followed by a WaitIO() after every AbortIO()...the Wait() is redundant, and it *will* occasionally hang). -Dan Riley (riley@tcgould.tn.cornell.edu, cornell!batcomputer!riley) -Wilson Lab, Cornell University
