Grex Micros Item 50: E71 or 7-E-1?
Entered by danr on Mon Apr 5 11:38:30 UTC 1993:

In the agora item about t-shirts, I first proposed the letters "E71" to
denote comm port settings of even parity, seven data bits, and one stop
bit.  tsty argued that "7-E-1" was better.  Personally, I've most often
seen "E71" and that is the notation my comm program, TELIX, uses.  I'd
like to use the most common or the most understandable notation if we
are going to print it on t-shirts.

So, I have a couple of questions?  First, what comm program do you use,
and what notation does it use?  Second, what notation makes the most
sense to you?

31 responses total.

My comm. program is MS-Kermit, which doesn't use either notation, and
in fact doesn't allow you to set the number of stop bits.  The docu-
mentation claims that the program automatically sets the number of
stop bits correctly based on the connection speed.

(I also use it at 8 data bits, no parity when I call Grex and have no
problems.  But that's only because Kermit provides a "strip high bit
on display" option which I have to set.)

7-E-1 is more appealing aesthetically to me than E71 because it's
balanced -- one digit on either side of a letter.

I'm, with Remmers on all counts, except I use 7-E-1 and don't strip.
I got in this habit because if there were a true 7bit network between my
MacKermit and Grex, file transfers would be hosed at 8 bit.
Since there isn't, I might be able to speed up transfers by doing it
remmers's way.

Stop bits not = 1 is only used at archaic speeds like 110 baud, I believe.

<<there +can+ be two stop bits, but I've never encountered it except
in readings about 9 or 10 bit modem-words.>>


#4 of 31 by danr on Mon Apr 5 22:07:03 1993:

(I think the programmable number of stop bits is a holdover from
tty days.  Some of those mechanical monsters needed the extra time
to process the character.)

I use Commo (the only thing that'll fit on this micro-micro), and
it reads 7e1.


#6 of 31 by jdg on Tue Apr 6 02:40:21 1993:

re:2-4, yes, I've *used* 2 stop bits.  110 baud.  10 characters per
second.  11 bits per byte.  1 start, 7 data, 1 parity, and 2 stop.
The years were 1969-1971, or so.
 
Wow, I even remember when I saw my *first* crt terminal, and 300 baud.
It was blindingly fast.
 
(you may now continue with the t-shirt item.)

Versaterm, which I'm on now, does it
   
          E
          7
          1


#8 of 31 by rogue on Tue Apr 6 06:41:49 1993:

Telemate does it E71. 


#9 of 31 by kentn on Tue Apr 6 18:38:03 1993:

(I thought you thought Telemate was incredibly slow and preferred Telix,
rogue?)


#10 of 31 by power on Tue Apr 6 20:49:24 1993:

ProTERM does 7E1.  I, also, call at 8N1, since the VT-100 emulation on this
doesn't distinguish between high bit set or not...


#11 of 31 by tsty on Wed Apr 7 04:54:25 1993:

Oh, also since E is the 5th letter of the alphabet, 7-E-1 ~7-5-1 in

nice numerical order, descending to a stop ... and is probably the
Daily 3 number for tomorrow, if you needed to know ......


#12 of 31 by ecl on Fri Apr 9 07:11:14 1993:

actually I call at 8 N 1



#13 of 31 by danr on Fri Apr 9 11:25:39 1993:

Since Grex seems to work at E71 or 8N1, maybe we should just leave that
line off the t-shirt.


#14 of 31 by mju on Fri Apr 9 12:33:17 1993:

It only works at 8N1 if your software strips the high bit off characters
(i.e., ignores parity).  Many pieces of software (mine, for instance)
do not do that, and I have to call in at 7E1 or text is garbled.


#15 of 31 by tsty on Fri Apr 9 20:48:30 1993:

Oh, no, some line like that just +has+ to be on the shirt - it's 

a phenominal conversation starter, trust me on that. Wearing the
"other" shirt, the prompt does the same thing, start conversations!
  
Something "cryptic" is the key ............


#16 of 31 by danr on Fri Apr 9 23:34:30 1993:

Good point.


#17 of 31 by bdp on Sat Apr 10 19:48:34 1993:

I've usually used E71 and N81.  N81 seems to roll off the tongue better than
8N1.  So does E71. :)


#18 of 31 by rcurl on Sun Apr 11 03:53:35 1993:

How about emblazoning 3697 across the front of the shirt?


#19 of 31 by steve on Sun Apr 11 16:10:17 1993:

   Telix uses E71, which goes against my grain.  I'd prefer it to be
7E1, although I can't say why.


#20 of 31 by kentn on Sun Apr 11 16:28:43 1993:

Why not use both E71 and 7E1?


#21 of 31 by rcurl on Sun Apr 11 16:53:48 1993:

There are 6 permutations. Why not *all* of them? Then everyone would
display their favorite. (Re: #18: 2033 is another possibility).


#22 of 31 by kentn on Mon Apr 12 00:18:38 1993:

Yeah!


#23 of 31 by rogue on Mon Apr 12 15:50:37 1993:

#9: I think you're thinking about someone else. Telemate is relatively 
    large and slower, but I'm running a 486DX2-80MHz machine right now with
    16MB RAM and couldn't care less. 
 


#24 of 31 by kentn on Mon Apr 12 18:12:01 1993:

Hmmm, thought you said something like that on M-Net.  Musta been mistaken.


#25 of 31 by tsty on Tue Apr 13 05:12:42 1993:

<<the numerical clue bus leaves Toasty standing by the curb ...>>


#26 of 31 by rcurl on Tue Apr 13 13:17:29 1993:

Still no takers. Would 383 be of interest? Nicely symmetric.


#27 of 31 by tsty on Tue Apr 13 21:10:20 1993:

Now that number I know - Chrysler V-8  - damn fine engine with
a 6-pak carburation. ZOOM!


#28 of 31 by rogue on Thu Apr 15 01:18:55 1993:

#24: John Perry said that on MNet, not me. If I am not mistaken, John Perry
     has a 20MHz 386 with 4MB RAM.


#29 of 31 by kentn on Thu Apr 15 02:27:55 1993:

Aaaahh!  Okay.  You see how easy it is to confuse things like 7E1 and E71,
John Perry and Jemmie...  At any rate, Telemate seems to follow the E71
way of thinking.


#30 of 31 by rogue on Thu Apr 15 10:18:05 1993:

Another problem with Telemate is that you have to have at least 500k of
conventional memory free. Again, I don't have a problem with that. The
reason I use Telemate is because of it's editing, viewing, cutting and
pasting abilities, etc. Very nice...


#31 of 31 by kentn on Thu Apr 15 20:59:40 1993:

Definitely.
