Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

the second set of changes in a move towards getting devices to be
totally dynamic.
this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.
For this edit,
each of the files has the following code inserted into it:
obviously, tailored to suit..

Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.

Digicom Systems Inc, makes "softmodems". What this means is simply that
you download the microcode to the DSP everytime you power on your system.
They provide a dos-program to do so, but no other support. This commit adds
code to the sio-driver, which implement an ioctl, which will down-load the
micro-code.
To get this functionality, you must define DSI_SOFT_MODEM.
The program to actually employ the ioctl is not included, but the entire
source looks like this:
#include <sys/ioctl.h>
#include <stdio.h>
main()
{
unsigned char buffer[100000];
int i;
read(0,buffer,100000);
if((i = ioctl(1,TIOCDSIMICROCODE,buffer)) < 0)
perror("ioctl");
return i;
}
And you use it like this:
smload < data144b.dsi > /dev/ttyid3
You need to copy the *.DSI files from the dos-media provide with your modem.
You can see what is downloaded by issuing the ATI3 command to the modem.
DSI's scheme for what code you can run on your modem isn't violated by this.
