SOME KERMIT PROBLEMS I AM HAVING
(I think they're Kermit problems -- but maybe they're just solaris <---> sunos
problems...)
1. CONTEXT: WHICH KERMIT VERSIONS USED:
local: sparcstation 5; solaris 2.5.1
C-Kermit 6.0.192, 6 Sep 96, for Solaris 2.x
remote: netcom.com (shell acct) sunos
C-Kermit 5A(190), 4 Oct 94, for SunOS 4.1 (BSD)
2. CONTEXT: WHICH MODEM: I have a Sportster 14.4 "faxmodem", on a
Sparcstation 5, using SOLARIS, connected by dialout to my SHELL
ACCOUNT on NETCOM (which has Suns and uses SUNOS 4.x)
(I also just bought a NEW modem, a 56K Sportster "faxmodem", but
which I am keeping in its box UNTIL I find out how to make my 14.4
work right!)
3. CONTEXT: HOW KERMIT SETUP:
By the way, here's my ".mykermrc":
set modem type usrobotics
set line /dev/cua/a
set speed 19200
set file names literal
set terminal autodownload on
And run with stty sane, terminal=SUN, and I run with on both local
and remote "csh", and for display, locally I use Solaris' "CDE",
but remotely, it's just a plain cmd-line login)
"show dial" vs "show modem" (both shown AFTER doing set modem type,
set line, AND set speed):
4. show dial:
Line: /dev/cua/a, Modem type: usrobotics, speed: 19200, carrier:
auto
5. show modem:
Line: /dev/cua/a, Modem type: usrobotics
US Robotics Courier or Sportster
Modem carrier-watch: auto
Modem capabilities: AT SB EC DC HWFC SWFC
Modem maximum-speed: 57600 bps
Modem error-correction: on
Modem compression: on
Modem speed-matching: off (interface speed is locked)
Modem flow-control: auto
Modem kermit-spoof: off
Modem escape-character: 43 (= "+")
6. PBM: CAN'T GET "CONTROL-\" TO WORK FOR KERMIT:
Well, once in a GREAT while, but rare. Please, what am I doing
wrong?
(Yes, the key works, since if I use TIP and then run remote EMACS,
what with flow control occupying C-s (and C-q), I have to do
forward search via "C-\" -- and it works!)
RELATED QUESTION: when using Kermit (with its C=\), what is the
USUAL solution to doing a forward search on a remote EMACS?
7. PBM: DOWNLOAD TRANSFER-SPEED MUCH TOO SLOW: the Kermit
download-display typically shows anywhere from 190 to 250 "cps".
EXAMPLE: it takes me FORTY minutes to download a .45-MEG (ie
half-megabyte) file -- and that relationship scales linearly.
That's .45mb/40min = (.45mb * 1min) / (60sec * 40min) ==> .45mb /
2400sec ==> 4.5bytes * 100,000 / 2.4sec * 1000 ==> 1.9 * 100
bytes/second ==> 1.9 * 100 bytes/second * (8 bits/byte) ==> 1500
bits/second, which is like one TENTH the rated 14.4 speed!
(Note: yes, two or so years ago, I sent the modem back to US
Robotics, and they returned it to me saying it was just fine.)
BUT, ON WIFE'S PC: My wife has a Pentium/OS-2, with a 28.8k modem,
and on HER machine, it takes me exactly NINE minutes (via her acct
on IBM.NET) to download 1.4mb (ie, a floppy's worth (I always do
that size, for sneaker net up to my machine).
8. PBM: downloaded file-NAMES get CHANGED:
(And yes, I do say "set file names literal"). TWO problems: (a)
filenames get UPPERCASED, and (b) although the FIRST "dot"
translates ok, any FURTHER dots are changed to "X", eg:
foo.bar.tar.gz" ==> FOO.BARXTARXGZ
And, Kermit must think this crazy name translation is just fine,
because right there in the download display, it freely admits what
it is doing, explicitly showing its name-translation!
Again, this is from SUNOS (remote) to SOLARIS/SPARC (local).
9. PBM: DISCONNECTING FROM NETCOM:
To exit netcom, I merely say "exit", which logs me off the remote
computer.
With TIP, I must then do "~.", which disconnects TIP, frees port,
etc.
However, with KERMIT, it just HANGS, sometimes forcing me to KILL
the entire local "SHELLTOOL" I ran Kermit from. My CURRENT
solution is to simply TURN OFF THE MODEM. There must be some
better way!
10. SILLY QUESTION: edit-number vs major version: is 5-190 IDENTICAL to
6-190?
11. PBM: NON-KERMIT PBM: RZ, SZ no longer works for me:
When, up through two years ago, I had a Sun 3/160, running SUNOS
4.1, I could TIP into netcom, and then quickly download binary
files (eg .tar.gz) via running "sz" there, and (via tip's ~C"
escape cmd) run "rz" here on the 3/160. and it all worked fine.
NO LONGER!, now that I have the sparc-5 and solaris, and have
recompiled "rz" here for solaris. No workee no more. Any ideas?
(Perhaps somehow related to above Kermit speed-problem?)
12. YES, I TOO USE "SCRIBE". Lets trade tricks, techniques, our own
documentation. What's your phone number? Mine's 914-632-1883 (New
Rochelle)
