Driver for RTL8139 for Coherent 4.2.10
client command works reliably , including download of gzipped
files (tested with vsFTPd 2.x)
of gzipped files in lynx 2.8.3 works reliably
fetchmail tested OK with dovecot POP3 server
version recognition works fine
environment : cable television (dhcp) connection 1500 Kbits
down/250 Kbits up
testing finished , our udp/tcp subsystem + rtl8139 driver are
usable and useful
testing started, goal : increased stability and performance, LAN
get, put , delete, ls commands work reliably
television dhcp 3000/500 Kbits connection works even better
in lynx2-8-3 works fine including gopher download(of text and
gzipped files(.z, .gz,.tgz ))
in lynx2-8-1 works fine
http server implemented, good for testing: because our network
subsystem does not have loopback feature, it can be used to test
lynx-www server connection on one PC(via dhcp).
cards : 8139c(full duplex), 8139d(half duplex). Should work on
systems, it does not mean we want to port Coherent to ARM
processors for example, but we mean dedicated applications, for
example robots using Intel/AMD proccessors etc, or Intel
machines controlling external microcontroller applications
connected to PC.
network (twisted-pair with switch/hub) test (LAN)
average 700 KB/s(5.6 Mbits/s) for big files(~100 MB) on local
network, both PC using Realtek 8139(c,d), full/half duplex or
both full/full via simple 10 Mbits switch
speed achieved using lynx and our http server , being good
method of file transfer between Coherent boxes
KB/s achieved (lynx file download) on cable modem with 3000
Kb/s(in) and 500Kb/s (out).Result comparable to that what I get
command and arp command implemented , are used in LAN setup
posting/replying fixed, works fine in lynx2-8-1
sending with mutt works , it uses our sendmail command (tested
with ESMTP, ESMTP/Postix(Debian))
tested once again, works reliably with POP3 dovecot, usually it
works in background as daemon
(inetutils 1.4.x) finally works fine, support for 8 bit
and works with both -DTERMCAP or -DUSE_TERMIO flags.
in cable television connection with Solaris 10 x86 telnet
service(inetadm -e telnet) : mc in color mode works fine, vi
editor works fine, ps -A etc, probably lynx and mutt work fine.
in cable television connection with nethack game server, one can
really play this amusing game, it is my number three favorite
after xtetris and xboard.
in cable television connection with Linux Aurox 9(clone of
RedHat) telnet service: mc, lynx, pine, vim and mutt work fine.
I can even play nethack game from this remote Linux. WOW , “top”
works too, looks like in Linux.Linux box and Coherent are
connected to the same switch and cable modem(my private LAN).
means it can be used with Telnet terminal server , as a terminal
to remote Solaris10
results with vt220 terminal TERM setting, but works with vt100
too, it does not work with ansipc setting.
x3270 3.1.1/3.3.7 works
fine.c3270(curses client) works fine(wow,22.5.2008).I have spent
8 years in front of green 3270 terminal, so it is a pleasure to
see it in Coherent again. Check this.Screenshot

1.2.2 ported, it supports protocol version 1.5.Tested with
openSSH 1.2.2 sshd server running in Linux.Nowadays mostly newer
version protocol 2 is used, but it is not a problem to have both
sshd servers running in Linux or Solaris system.Tested
configuration was the following : ssh client behind the hardware
router with hardware firewall and sshd server running behind the
software iptables firewall. Doubly secure combination.Quite
stable.One can observe top program on the other Linux side for
Above means that openSSL was
ported , version 0.9.6a.For example small demo cli works fine
with serv demo running in Linux.
December the 17th 2008
support enabled in our previously ported mutt 1,4i.
imaps secure protocol in
mutt tested with our University imap server running in Linux
.Stable and fast.I like it.
January the 20 th 2009
iso-8859-2 support ,mostly
for mutt, designed and implemented. It allows to send mails
using Polish Latin2 letters , which can be shared as expected
with Linux/Solaris world.Very important to make mutt useful for
me.It required patch of virtual nonloadable console driver vtkb
and special program to load Polish latin2 fonts , fonts which I
have designed myself about 14 years ago.
openSSH 2.1.1.p4, with
support for 2/1.5 protocols, tested with newest
Fedora,Debian,FreeBSD, Solaris10 sshd servers
lynx 2.8.6rel4 , with https
support, really colorful (color styles); http and news(nntp)
Download speed in lynx the
same as in Linux/Solaris using 3COM 9xx and the same cable TV
connection; PC's connected to router , which in itself was
connected to GrandStream SIP phone working as switch, which in
itself was connected to cable TV modem
BTW , driver works fine in
10/100 Mbit modes
newest libbind 6.0 from isc
dig 8.4 from libbind 6-.0
works fine, using tcp only.
now lynx-2.8.6 using libbind
resolves names in Internet much better, one can google for
/etc/resolv.conf is used to
define dns servers, OpenDNS
servers were tested.Our ISP dns servers also work fine.
corresponds to /etc/host.conf : order hosts,bind
configuration, but host.conf is not used.
We now use cisco 10/100/1000
switch, realtek cards are set to 100 Mbit duplex mode using
support for UDP sockets
as a test of above ntp-4.1.1
was ported, but not completely ntp.org
ntpdate from ntp-4.1.1 works
fine , it does get time offset from the public time server and
sets/adjusts the system time accordingly. I had to add some code
because Coherent does not have adjtime system call. Of course
added code does not „discipline” system clock like in
BSD/HP-UX but only modifies system time. One of the problems is
to choose best time server.
example : ntpdate -u
Time synchronization in Internet
is a fascinating and a very sophisticated topic .
supports builtin smtp(s)
uses OpenSSL 0.9.6x
works like a charm,
tested with Exim, Postfix,
our own external sendmail
can also be used if for some reason builtin smtp has problems
(uses LOGIN,OpenSSL and TLSv1)
we use lynx/links to view
html mail attachments
19.12.2013 : we use zgv to
view image (png,jpg etc) mail attachments , it required porting
Todo : traceroute ...
