RS232 Communication could be done in SW, you'd need
minimum 2 free port pins and you will need a driver
written to use this pins as UART. Further you'll
need a converter to RS232 Level, (most people will
use MAX232 | friends for that) to convert TTL to RS232.
If you need handshake you need another 2 pins,
if you need some other stuff, 1 pin for each.
some reasons why you might not want to do this:
-software UART is CPU expensive
-developing and testing such drivers is expensive
(maybe there already is one?)
another option you might have:
you could use some bilateral CMOS Switches to
redirect the serial port of the µC at runtime.
redirect the serial port in Hardware to
an additional debug DSUB Connector, this way you could
watch it booting. When booting is done the serial port
is redirected to the modem and everythings fine.
Redirecting is done by a bilateral CMOS Switch,
Maybe there is a simple way to reject the serial message
in software, but might have a hard time in debugging/testing of such a
system.

Subject: IDE vs SCSI ZIP drives
Date: 3 Nov 2000 23:08:54 GMT
Im having a problem that SOMEONE must have seen before.
If I check the size of a Zip Cartridge (copy /dev/zero to it with dd)
I find the cartridge is 16k if it is mounted in a SCSI drive than if
mounted in a IDE drive.
No probem you say.
Well, the real problem is that a ZIP cartridge partitioned/formtted on
the IDE ZIP drive is not readable on the SCSI ZIP drive. Seems the extra
16k appears at the beginning of the SCSI cartridge (as far as that drive
is concerned) and as such you dont see the MBR wriiten by one by the other.
Does this sound familiar to ANYONE?
ANYONE else have problems transfering cartridges between ZIP drives on
the IDE and SCSI?
[ As long as a cartridge is ONLY used by IDE or SCSI drives you will never
see this problem]

I'm not sure why but I seem to cope better without imwheel. Most gnome
and kde stuff now has automatic scroll wheel detection as does wterm
(and probably most virtual terminals).
There are also some lines for xemacs that you can add to you
.Xdefaults - what else do you need? I just find that imwheel makes it
all more jerky.

I too have all Linksys, excepting a card in a PPC. This is the second set
I've had, running a linux box and linux router, with a 'Doze box also
with the 1st set. Both sets worked straight away in RH 5.1, 5.2, 6.0 and
now 6.2. Had to get the driver for Mandrake and Debian.
My advice has always been, try the driver you start with first. If that
doesn't work, get the new one. If that doesn't work, ask. There are
other drivers floating around that other users know about and can
point people toward.

Subject: Enabling dma
Date: Sat, 04 Nov 2000 01:05:29 GMT
My setup is as follows:
ASUS P3B-F motherboard, which has the Intel 440BX chipset.
two Seagate hard disks, 10GB ST310212A and 20GB ST320423A.
RedHat 6.2
I can enable dma on the hard disks using hdparm -d1, but I have to do
this every time I boot. Someone told me that if I use -k (-K?) it would
remember the settings, but that didn't work for me. hdparm reports that
the 'keep settings' flag is set, but after rebooting the settings are
lost.
The UDMA how-to says that if the kernel doesn't automatically enable dma
then there is probably a good reason and I shouldn't do it either.
What could be the reason that dma is not automatically getting turned
on? I turn it on in my rc scripts now, but is this a bad idea?
Thanks,
Cary

Dear All,
My box have 3 nic installed , I would like to use this box as my firewall
with DMZ,
Those card was loaded up successfully during LILO. And I have assigned the
following IP for each interface as follow :
============================================================================
eth1 : 168.168.1.254 ----- For our Private LAN (Intel EtherExpress Pro100)
netmask: 255.255.0.0
network: 168.168.0.0
broadcast: 168.168.255.255
eth2 : 168.168.2.254 ----- For our DMZ (Intel EtherExpress Pro100)
netmask: 255.255.0.0
network: 168.168.0.0
broadcast: 168.168.255.255
eth2 : x.x.x.x --------------- Which is our public IP (3c905B-TPO)
Also, I have set up 2 PC for test using crossover Cat5.
PC1 (simulate as Private LAN client)
- connect to the "eth1"
- and the IP is 168.168.1.10
netmask: 255.255.0.0
network: 168.168.0.0
broadcast: 168.168.255.255
gateway : 168.168.1.254
PC2 (simulate as DMZ's server)
- connect to the "eth2"
- and the IP is 168.168.1.10
netmask: 255.255.0.0
network: 168.168.0.0
broadcast: 168.168.255.255
gateway : 168.168.2.254
============================================================================
After those setup, I started try to ping those test PC at the Firewall
box.
but just the PC2 have response.. The interrupts of those eth0 and eth1 are
keep
increasing.... so, will this is the routing problem or what other else ??
Does anyone experienced this wired things b4 ??

As I understand it, the -k setting restores but does not initiate UDMA;
that is, if for some reason UDMA is lost, -k will check and restore it.
But it is not designed to start it at bootup.
hdparm reports that

The How-Tos are notoriously conservative.

It might trash a drive that doesn't support UDMA; there are many such old
ones out there still in service.
>I turn it on in my rc scripts now, but is this a bad idea?
I turn mine on in rc.d. It also works from etc/profile, but I understand
rc.d is the preferred place to put it. Write it out just as you turn it
on manually. You will see the notation (last before root prompt) when you
boot next.

Got me, but remember that there are 2 different types of "IDE" ZIP
drives. The earlier model was a straight IDE device, and uses the IDE
disk driver. The later model was ATAPI, and uses the ide-floppy or the
SCSI emulation layer Linux has.
If your IDE ZIP is one of the old models, there may not be much you can
do! I've heard of a number of weird problems with those drives that
don't occur with the newer ones.
I suppose you could try adding IDE-SCSI emulation, SCSI support, and SCSI
disk support to your Linux system, then telling your machine to view the
ZIP as a SCSI device. This *might* smooth over any compatibility
problems, but then again it might not.
FWIW, I've transferred the same ZIP disks between IDE, parport, and SCSI
ZIP drives under 4 different OSes (MacOS, Win9x, WinNT, Linux) and never
seen a problem like this before. Anyone else know something I don't?

David Hinds's PCMCIA-CS package, and the pcnet_cs driver within that.
http://pcmcia.sourceforge.net/ if nowhere else. BTW, you really should
update that install unless your laptop is < 16M and < Pentium90. The
