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.

This puppy is in good shape now.
It is a fully blown SCSI-driver, but it isn't a high performance one. It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes. It will run disks and tapes if asked to, but it isn't a
very good idea to do so. Transfer-rates max out at 600-700 kbyte/sec.
There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls. This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok. I have circumvented this by disabling the
pseudo-DMA in those cases.
It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.
You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.
I will fix any bugs I can get a handle on.

if KERNEL is not defined. lib/msun/i387/*.S include asmacros.h to

the ".type" declarations. This caused the linker to print warnings
about doubtful relocations for almost anything linked to libm[sun].

add lpctl? devices (minor # = unit + 128)
- usr.sbin/Makefile add lptcontrol
- sys/i386/isa/lpt.c implement the LP_BYPASS flag: when a unit is
opened with this flag set, the printer is
not primed, and no check is made to see that
the printer is online. This can only be used
to pass ioctls. (giving us /dev/lpctl?)

Update the if_ep driver for the 3C579 and bring over some of the
changes from the netbsd driver.
This is not complete: the detection of the irq in the eisa does not
work and sometimes the reset for the 3C509 in ISA in an EISA bus system
don't work ( Need a hard reset to be found again == reset knob).
DIOCGDINFO, DIOCGPART, DIOCWDINFO, DIOCSDINFO, CDIOCPLAYMSF, CDIOCRESET,
CDIOCEJECT.
CDIOCPLAYBLOCKS removed (old implementation completely wrong and I don't
know how to implement it correctly).
All routines now detects media change correctly.
DELAY_GETREPLAY increased for long time access from first track
to last.
mcd_waitrdy() now use MIN_DELAY=15 as minimal delay which independs
of machine speed.
mcd_doread() now uses real status (old code uses obsoleted soft copy of it).
clear XBSY on error in mcd_doread()
mcd_statrt(): add missing splx(s), cause dead hang with unmatched slpbio()
optimize mcd_doread(), don't set CD mode each time, keep soft copy of mode.
call getdisklabel() _after_ mcdsize() for proper sizes
mcdopen(): old code forget to set MCDREADRAW in flags when open RAW
partition, doread check it for setting RAW CD mode.
Do nothing on stray interrupt (which sometimes occurse, because driver
read data block too slow, DOS driver use 'insb' here). Old stray code
cause timeouts.
Read toc entries code rewritten to return many requested entries
(as supposed) instead of one entry with incorrect structure.
CMDREAD2 requests covered with disable_intr()/enable_intr()
(from DOS driver)
Read junk code added after read block code in doread (from DOS driver)
mcd_read_toc() code fixed to read all needed entries, old code cause
some audio tracks is not played.
mcd_playtracks() code fixed to proper check valid track range.
New binary read modes implemented (from DOS driver).

Put the printf("can't map 3c507 ram.. into an ifdef DEBUG. This will
confuse only normal users and the ie0 found/not found is sufficient.
Submitted by:
1) if_ie.c:
Changed a printf and put a space in it. Formerly the "<3C507>"

log that message.
2) isa_device.h:
Changed the iobase variable from short to u_short. EISA
Adresses can go up to 0xf000 and the sign extension doesn't
look good in the probe output. Example:
ep1 at 0xffff8000-0xffff8000f is not good :-), i like more a
ep1 at 0x8000-0x8000f.
3) isa.c:
Changed a string constant from "probe" to "prob", it gets
later already an "ed" tagged on the end.
Added "device pci" and "device ncr" lines for a generic kernel with

configured, ie. working with 100Hz timer interrupts only).

bogus dependency was used for machdep.c and there was never anything
special about the others.
Add locore.s, but commented out. It's still special.
Remove com.c and lpa.c.
SYSTEM_OBS. They are now normal objects.
Remove stale dependencies for the above now-normal objects and for
locore.o and generate dependencies using mkdep. Config doesn't
generate lists of assembler source files so the lists to be mkdep'ed
have to be given explictly. Only the standard *.s files are given,
so the dependencies for gnu/fpemul/*.s are incomplete. *.S files
would be handled right if config put them in CFILES.
Don't define NPX. It was replaced by NNPX > 0 years ago.
Define LOAD_ADDRESS in COPTS so that compiling machdep.c isn't a special
case.
Moving around the dependencies exposed a bug in make. It doesn't
know that assym.s and ./assym.s are the same. Add a rule tell it.

2) Added ps ddb function from 1.1.5. Cleaned it up a bit and moved into its
own file.
3) Added \r handing in db_printf.
4) Added missing memory usage stats to statclock().
5) Added dummy function to pseudo_set so it will be emitted if there
are no other pseudo declarations.
2) DELAY(1) does nothing, it affects audio playing f.e:
driver can't play second half of disk, changed to DELAY(10)
3) Debugging messages #ifdef DEBUGed
find something useful to do other than taking credit for other people's
work. Also make the 3C507 bits match the indentation style of the rest of
the code.
Merged changes from 2.0 version (revisions 1.46-1.50) by hand.
Finished conversion to clists: removed flush of tty output buffer
in comflush() (most writes were truncated to 256 bytes) and restored
bypass of ttyinput() in siopoll().
Finished conversion to 2.0 types - more void *'s, less caddr_t's,
less casts, no Dev_t's.
Only these things are seriously broken now compared with 1.1.5:
waiting for output complete is impossible so ttywait() can deadlock;
sioclose() isn't called enough so sioopen() sometimes returns EBUSY
unnecessarily; input flow control is not implemented.

Add the 3com 3C507 card to the if_ie.c driver. The files elink.c and
elink.h are helding routines that are shared between the 3C507 and the

The code is based on the NetBSD driver if_ie.c donated to NetBSD by
Rafal Boni and then modified by Charles Hannum.

revision. They caused redundant redeclaration warnings because I
forgot to declare them as extern and gcc-2.6.0 treats "extern int x[];"
slightly different from "int x[];" (this is probably a bug). The new
versions will cause RR warnings from gcc-2.4.5 because it does not
understand that the second declaration in "extern int x[]; int x[1];"
is not redundant. The variables don't actually need to be declared
in a header file because they are used in only one C source file and
one assembler source file, but I want all public variables and
comments about them to be findable by grepping *.h.
