[comp.sys.amiga] VT100 question

cmcmanis@sun.UUCP (04/15/87)

Has anyone besides myself noticed that the ASCII Send option of Vt100 (2.6)
is *really* slow? Anyway to speed it up?

These opinions are my own and no one elses, but you knew that didn't you.

You ain't gonna believe this one... I noticed the same thing while
working on a machine without Kermit (well, with a lousy Kermit anyway).
Try clicking the menu (right) button a few times. NO I'M NOT KIDDING. 
Don't ask me why but hey, it works! It might also help to dance 
around a bit and chant to the gods... ;-)

Yes.  The problem is that main() does a send of a file by doing a
getc() followed by a single sendchar() followed by a Wait() on all the
signals again--i.e., it sends a character and waits for it to echo,
then sends the next one, etc.  Not only is this slow, but it hung when
I tried to use it on BIX, since I normally run BIX half duplex to save
time and BIX wasn't echoing the sent characters.  I implemented most
of a fix last night, replacing the getc/sendchar pair with a
fgets/sendstring pair (replacing the trailing newline with a carriage
return).  I'll try to post the diffs sometime this weekend.

This works because clicking the right button gets out of the
aforementioned Wait() call.

It does that with me only during the first line.
From then on (without clicking anything), it seems to work fine.

Hello!  Yes, it's my third question in only two days, but please bear
with me.
  I have found a perfect term-em setup, sort of... using VT100 v2.3
I have low memory usage, kermit protocols, and it works on the workbench
so I can call up other windows to use with it.  Only one problem--

  How can I get the Sun I hook up to to recognize the amiga backspace
key as a backspace?  Currently backspace only puts control-H on the
screen, and I have to use the delete key to backspace.  As long as I'm
asking, how can I get the delete key to just do a normal forward delete?
  I hope someone knows how to answer these questions...

You can accomplish this in one of two ways:
   1) issue an appropriate stty on the SUN (man stty on the SUN for more
      info)
   2) upgrade to a newer VT100 and either issue "SWAP ON" in your
      vt100.init file or hit the SWAP menu selection in the Utilities
      menu.  SWAP will swap BS and DEL.
