Oops sent this direct to Steve instead of the list.

BTW, I just found the programming info for the Dataq 8 bit adc board.
It can be dound at:

http://www2.dataq.com/techinfo/dataform.htm

The DI-194 is a $13 (US, P+H extra). Not a bad deal.

Still working, I just found Dan Lanciani's X10d for the CM17A
(Firecracker) and either the MR26A or Dave Houston's AHT (a BS2X board).
Both provide wireless X10.

I'm currently tide up with my HCS II, searching for LonWorks (we may
have something here) and OnQ. I'm working on articles and such so I'm
tied up with that. Sorry about no push on the LHA project. It's not
forgotten and I'm actually hoping to take advantage of a few other
things I'm working on. Currently I'm in heavy research mode. Oh I'm
also working on getting a Linux 2.4 system together. Someone has
pointed out that there are problems compiling various code on that.

Hmm, I really guess I should be sharing the info here. I just haven't
had a lot of spare time to settle down and get things done.

2 other things, the first is that I'm stuck working on my friend home
(for at least 3 more weekends, argh!) and I really need to get to work
on my web interface. I have the PHP code (PHP/Apache/SSL/MySQL/Homedaemon
/X10d/Javascript) working but someone else had trouble with it.

Of course I'm still here. :-)

[LHA-misc] Newbie Linux Serial Port Question

[Lloyd F. <llo...@us...>]

I want to control an RS-232 device from my Linux box.  It uses a very 
simple serial protocol and ideally I would like to write to and read from 
it in a shell script.

Can anybody point me to some resources that explain how to access the 
serial port from shell scripts.  Eventually, I would like to do it in C or 
Perl but that is beyond my ability with those languages right now, any 
pointers to resources on this would be appreciated for future reference.

Also, can anybody recommend a simple terminal emulator to allow me to 
communicate with the box directly (something like hyperterm)?  I have tried 
mgetty and a couple of others but they all seem to want to configure a 
Hayes modem, and make connections to other machines, maybe I just need some 
help with configuration.

Thanks in advance.

That's going to be very difficult, I'm not even sure it's possible.

For C, a book called "Advanced Programming in the Unix Environment" by
Stevens.  Good book, he has a few more books that are similar, including some
good ones on TCP/IP.

I haven't done anything like this in perl yet, but I know there are a few
modules on www.cpan.org dealing with serial ports.

Excellent program called minicom.

Sure.

echo "Serial-protocol-commands" >> /dev/ttyS0 

(/dev/ttyS0 is usually serial port 0 under linux)

Also, check out stty, which should allow you to set the attributes of
the serial port.
Eg. To see the current setting of serial port 0, 

stty -F /dev/ttyS0 

To set the speed:

stty -F /dev/ttyS0 speed 38400

[LHA-misc] Keyboardless Server

[Lloyd F. <llo...@us...>]

I have acquired an old P100 tower and would like to use it as a home 
automation server accessed via Telnet and/or web browser.  Does anybody 
know how to set it up so that it does not require a keyboard to boot?

Re: [LHA-misc] Keyboardless Server

[Ben S. <be...@bu...>]

Usually the BIOS has a setting for this - something along the lines of
"Fail on all but keyboard" - Ie. if the keyboard is not present, don;t
fail the boot process.

If it happens to be a Compaq, it may be more difficult, but there are
ways - post again if the BIOS solution doesn;t cut it.

Cheers, Ben

Re: [LHA-misc] Keyboardless Server

[Lloyd F. <llo...@us...>]

This is a great group, thanks to everybody.  I found it under something 
like error in the BIOS, have never looked there before assuming it would be 
something to do with Keyboard.

Thanks to everybody.

[LHA-misc] Linux Behind a Router

[Lloyd F. <llo...@us...>]

This is probably not the correct forum to be asking a networking/security 
question but perhaps someone has been through it and can give me some 
pointers.  When I get it working I fully intend to use it to remotely 
control some X-10 stuff connected to my Linux box:)

I have recently had a cable modem installed and purchased a SMC Barricade 
Router and signed up for dynamic DNS at d2g.com.  I would like to access my 
RedHat Linux box for Web, Telnet, etc. from the outside world.  Starting 
with Telnet, I think I have got the firewall configured correctly to pass 
port 23 through to my Linux box but when I try to log on, I get "Connect 
 From Unknown" and "Can't get Client Address" when I look at 
var/log/secure.  I have had similar problems telnetting in from machines on 
my local network and have found that I must add their IP address to 
/etc/hosts.  I've tried adding the address of my firewall and the current 
external IP address to /etc/hosts as well as the entire subnet of the 
external IP address to /etc/hosts.allow with no success.  I have similar 
problems and log entries in my Apache web server logs.  Does anybody know 
how to allow a limited dynamic IP address to get access to the server?
