Subject Puppy modem ? Understand hardware then understand software ?

There are only two serial ports switchable to four serial ports for external modems, which is very easily detected and installed. You can have four modems and four telephone lines in a software bbs system connected to four subscribers. Each subscriber has to read their downloads, and can share one computer delivering bbs material.

Internal modems use a PCI bus, which share the cpu by south and north bridge. And each PCI bus has 4 ISA buses included. So, you can have as many internal modem as you wish using maximum PCI slots for a bbs system. /dev/modem detects them by PCI slots, and connects them by software serial port assignment and priority(irq). On ambiguous devices made into modem, you need to detect the device chipset install the firmware, then the drivers can be installed. We did it in kernel 2.4.x. Now kernel 2.6.x do firmware in udev /usr/modem. Now only Puppy bothered to do any internal modems. But they may only work in Barry's laptops or desktops. Because of the architecture of his PCs is different from other laptops and desktops, our internal modems do not work in Puppy OS.
Barry has to uinderstand all the PC architecture to understand Puppy software requirements.

Now that most newer laptops are USB centric, WiFi/n will be among all the USB devices and some may still need firmware because of ambiguous devices being used on older USB devices. Newer USB devices should all have firmware in the ambiguous devices because memory is so cheap. So, Linux kernel udev will be obsoleted when firmware and drivers come with USB devices such as USB hdd, USB printer, USB monitor(no video card or VGA connector like dvd portable player watch TV), etc. Puppy has to look for these self sufficient USB devices to get them to work first, then cover most of the older USB devices. Then Puppy will be efficient if Older computers also use these new USB devices.

No use beat up dead horse, doing older USB devices without their included firmware and drivers. Linux 2.6.x started too early in year 2002 to depend on udev. Try to qualify some newer USB devices and see how their firmware and drivers works in your operating systems? In the uS, most public places even store offer free WiFi, so USB WiFi/n(edgeQam 16/64) has to be connected ASAP on bootup?

When you understand USB0-3, you may start to wonder why or how you can use USB127? USB127 can not be USB0-3 which is serial ports. USB 128 ports are memory addresses that are software ports to input and output data. Do you switch these 128 ports into the 4 serial ports? And what is the standards of memory addresses defined for 128 ports for USB 2.0; then what is USB 3.0 standards for USB memory address switching? What if you google USB address switching wiki?

You can see that old IBMPC is becoming a different animal(computer architecture), the minute you start thinking about USB memory address switch for data port(channels) and storage devices? USB architecture is software files not in gcc or Kernel 2.6.x dynamic library?

Do you have a partition software at the upper memory limit to define data channels from USB ports and dedicated swap file(cached memory) same as hdd partitions in zero track zero sector? USB memory banks will be installed in 0-ff address in the beginning of drams.

Its better to define it in Puppy woof, before a rush to release an obsoleted operating system with only 4 ports to output any data? Ralink WiFi/n can do 16 or 64 data edgeQam channels simultaneously from 128 USB data ports? The architecture of such parallel structure had been planned years ago from 500 channel edgeQam transceivers commercially to Ralink /n WiFi; now from cpu(DSP) to 128 ports of USB channels of data? You can see the most important cpu job is data transfer from the internet downloads and uploads. Satellite, wired and wireless transmission all use 500 channel edgeQam transceivers? Yes, indeed!

You are now a part of the history of computer architecture design change from digital data to radio frequency carrier analog/digital mixed signal data transfer technology. Some day USB memory banks(0-3) to contain 128 ports each to each 512 edgeQam channels to go directly to maximize capacity per transceiver thru USB Ralink WiFi/n mesh(0-7 or more IF channels).

Re: Subject Puppy modem ? Understand hardware then understand software ?

Using XP sp1 on Dell c610, the internal modem can be found in device manager as PCImodem. To install it, goto a list and find hsf modem(some had pctel instead) and installed it. You could also install on comm1, a standard external 56k modem. Or on USB find a modem.

This does not install modem in dialers. The sequence of modem finding is ports first to find the hardware, then instal firmware, then install drivers, then test at commands to verify the drivers and hardware working. Then the dialer tests dial tone, and handshake with iSP in the dialer and connects to ISP and your browser.

Internel modem has to test all the PCI slots on north and south bridge first?

In linux, ports are in /dev, not /usr? Symlink to /dev/modem and find the hardware can be then tested. Its easy to do external modem on serial ports, but PCI modems are listed in the bios by PnP, 4 digit numbers of the chipset. Bios findings are in the shadowed bios in upper memory in the drams. Microsoft device manager has all the devices discovered by PNPOS in the bios. Linux does not use PNPOS to its advantage So, the drivers are not found on ports(memory addresses) defined in IBMPC architecture.

Its a serious problem with Linux, and hardware compatibility is still a serious problem; I have to go back to XP on laptops with fixed peripherals(not interchangeable to devices Linux had drivers).

Re: Subject Puppy modem ? Understand hardware then understand software ?

The concept of TV remote is hibernation and instant on; use very little battery power which last many years in normal use. To do touch screen terminals like TV remote is the future of cellphones with USB terabyte mainframe computers plugged in.

To do Linux TV remote to run computer operating system, we need small change from squarshfs with operating flash codes instant on(or forever in hibernation in execution area of 16 mB), icon activates apps in OS stored in 64mB area. Flash memory can do instant on and save battery power. USB mainframe computer architecture does not need power until apps turn them on, on the USB bus.

The concept of using TV remote to control internet, has many advantages. And the concept of thumbnail pictures to transfer data will lead to thumbnail LCD monitors to save power from batteries.

MIT has had experience in wearable computers, everything on the eye glasses including the cellphone in the future designs. No hands Mom? Voice control, thumbnails near the eyes, and hearing near the ears; frame is the antenna.

OSes(windows) today cost too much to be used in desktops. netbooks will still shrink down and save battery power. Wearable is the ultimate computer and semiconductor industry can do it with nand flash memory and 8 bit DSP analog digital mixed signals for ultimate data compression. Every small step on the OS design has to be able to do the ultimate design?

Thanks you.

Computer controls are too slow compared to TV remotes.

In all the window managers, the lack of zoom features(FPU) made it fixed in resolution depending on media's original resolution as it transferred. I actually like it because the screen displays smaller faster. If I need details more, then I zoom to full screen. JMW if using FPU can zoom to any resolution large or small.

If data is in Mjpeg+MP3(mpeg4/h.264), then data transfer can be reduced pixels(thumbnails), then zoom to full screen in your computer. Internet traffic will be much faster.

This is the reason that we are changing computer protocols to consumer electronics protocols. VGA to HDMI(pin outs). Digital video to analog/digital mixed signals for more data compression capability(IF edgeQam channels).

The change will enable the whole world on the internet with massive parallel data processing of 128 ports of USB in your computer. USB devices will all have an IPv6 address? IBMPC will have different architecture, One bus standard but more data channels for multicore(128 small 8 bit cpus) approach, borrowing IF(intermediate frequencies) from radio and TV data channel design..

Re: Subject Puppy modem ? Understand hardware then understand software ?

Only dialup modem worked is the external modem using /dev/ttysx. This is because it has a irq of 3 or 4.

Internal dialup modem has to have firmware of sound chipset or DSP firmware to do functions of a modem. then the drivers assign irq of 11 or 3 or 4 of serial ports.

So far only external modem works with the old /dev serial port assignment.

The problems of internal modems udev can not assign any decision of finding the internal modem, let alone find the correct firmware, then finding the working modem drivers. Some one should strip out all internal modem modules. Then do Alsa firmware, and install at least pctel modems if found sound chipset for modem on the pci bus?
