Minicom and Modem


Hi All

Sorry for the posting. I have tried for two weeks to find my previous set of 
Minicom notes but. 

Anyway hopefully some nice person will help.

I have this computer connected to another computer by null modem cable. This 
is not the first time for this so I know that the other computer is working 
correctly but on this box I reinstalled the system after a major screw up. 
Apparently that was when I lost my minicom notes.

Anyways I have two serial port possibilities /dev/ttyS0 and /dev/ttyS1.
If memory serves me correctly I used ttyS0 previously but either way I have 
tried both.

The problem is that minicom does not see the serial port and I never establish 
a connection.

Again if I recall correctly I had to issue a command from the terminal to 
initiate so that minicom would see the serial port but I can not recall the 
command.

Damn I wish I had my notes back.

Anyway hopefully some one will know what I am talking about and can help.

Thanks

Linux Documentation

Hi,

I just stumbled on a web site http://en.tldp.org/guides.html

The Linux Documentation Project (LDP) is working on developing good, reliable 
documentation for the Linux operating system. The overall goal of the LDP is 
to collaborate in taking care of all of the issues of Linux documentation, 
ranging from online documentation (man pages, HTML, and so on) to printed 
manuals covering topics such as installing, using, and running Linux. Here is 
the Linux Documentation Project Manifesto and Copyright License for LDP works.

I found it interesting and thought this list might too.

IIRC, most distro's link /dev/modem to /dev/ttyS1 as default, or dont set it 
at all.

Either you dont have a link to the correct comport in /dev or its set 
pointing to the wrong device.

If its com1 then do as root;
cd /dev
rm modem

Re: Minicom and Modem

Hi

Thanks for the help. I greatly appreciate your taking the effort to respond.

Unfortunately I do not understand exactly you are saying in relation to this 
issue most like because I did not phrase the question correctly. Also I had 
forgotten that this is a dual boot box ( I try to forget the other half.) so 
all I had to do to check if it is /dev/ttyS0 or /Dev/ttyS1 was check 
Hyperlink. I definitely have com1 which is of course /dev/ttyS0 so I reset 
that in minicom accordingly.

Which I believes brings me up to the issue of minicom not seeing the modem 
which I believe you addressed as:

> Either you don't have a link to the correct comport in /dev or its set
> pointing to the wrong device.
>
> If its com1 then do as root;

> rm modem
> ln -s ttyS0 modem

All well and good but here is where fear of trying the above and destroying 
what I have combines with ignorance to produce intransigence.

Simply put I do not have a modem connected to the serial port.
My modem is an internal modem which works very well on Kppp.
What I have connected to the serial port is a null modem cable so that I can 
transfer files from one computer to a special process computer with the only 
access being a serial port.

Why use minicom at all for simply transfering fies via a serial cable.?

Simply configure the device on both sides with slattach or dip and make sure 
both have routes to each other, its a simple network then not a complicated 
thing with minicom.

Network card and kernel module problems

Hi all,

I use a Surecom EP-320X-S 100/10M Ethernet PCI adapter; I believe it's
Myson MTD3xx compatible --- at least, I've used it before with Myson's
fealnx.o module in Red Hat Linux 7.3.  The problem is I upgraded to RH8.0
and find that the kernel does not already support the card.  I tried
recompiling with built-in support (for the Myson module).  kudzu detected
the card at startup and configured it.  I've set it up it using Red Hat's
``neat'' tool (it uses DHCP), but it says it can't determine IP
information, and to check the cables.

Also, could anybody tell me of a way to check the various distros' kernels
to see if they come with built-in support for my card?

Help is much appreciated.

Yawar Amin

Then that means the card was detected and the module was loaded, have you 
done what it says.????

You may need to use dhcpcd with options to obtain a IP# from your isp.
IE, hostname ??.

Because that is the only way to make the transfers unless you know of a better 
Linux replacement of MS's Hyper Terminal than Minicom.

The second computer is NOT a Linux box or a MS box but is a specialized 
process control computer whose only access is by Hyper terminal under MS 
Windows. I am attempting to using Linux in this computer (the command 
computer) with the objective of replace MS's Hyper Terminal with Minicom 
under Linux.

Please I don't want to get into the configuration of a Sweitzer system (the 
system being controlled) on this list. Suffice it to say that it is not Linux 
nor MS.

I only want to configure Minicom under linux in the format in which I 
previously had it before I lost the Minicom installation instructions.

Sorry i was under the impresstion that both machines were linux.

Simply start as root, minicom and use -s
minicom -s
change the port setting to /dev/ttyS0 (i belive you said com1)
make sure the speed is correct and it should work.

Yes it possably would, disregard what i said about /dev/modem.

unable to make dep; limit.h


I hope someone can point me in the right direction. I tried to compile a new kernel (version 2.4.20) and I
ended up with the following error message:

[root <at> jetty linux-2.4.20]# make dep

I currently run Linux kernel 2.2.22 on a pentium laptop and RedHat 6.2 and I would appreciate any help or
suggestions as to where to look. Thank you!
