Subject: passing messages between dosemu/Linux
Date: 7 Jun 1994 19:00:13 GMT


Is there an easy way to talk to a program running under dosemu (a
very nice speech synthesizer, i wrote) from a Linux process?  

I considered using a file in /tmp, but the hardrive would be
constantly reading/writing.

Can both doesemu and linux share an ethernet card at the same time?
A TCP/UDP/IP socket would be easy to implement...

Can someone suggest an easier way?

Thank you.

Hi.  What do Linux users do about sharing filesystems ?
NFS is tied up in a SUN license (?)  What about AFS ?
I've used SMB on other UNIX, but it seems a little inadequate
for unix<->unix sharing.  Any info is really appreciated.

I know what you mean:
Do a little experiment
 1) Format a disc to MS DOS 1.44Mb using RISC OS 3.x
 2) Format a different disc using MS DOS on a PC or under emulation
 3) Save a big file to both discs..
    The Arc formatted one makes a lot of noise and is much slower (at least
    on my machine)
They both seem to work OK though... what's the difference? (anyone??)

They seem to work most of the time on a friends Linux machine (1.44Mb)...
You could always format the discs using one of the PD DOS readers that were
around before RISC OS 3.* arrived, but you probably wouldn't get 1.44Mb 
support - maybe format using the PCEmulator or PC card?

: Why did you tell it your name was "ftp"?  Common practice for anonymous

Most servers treat "ftp" and "anonymous" identically, and "ftp" is
easier to spell. :)

Of course, if "ftp" doesn't work, then I get out the dictionary and
try "anonymous."

Using the fastest timing waveform in the manual, I extrapolated to the
fasted dot clock my video board can handle, and came up with the
following mode line which works extremely well.

# 1024x768 @ 95.3Hz
"1024x768"      100.2   1024 1048 1152 1312     768 768 770 802

Talk about low flicker!  Now I just need to get more video memory
so I can increase the resolution.

Oh goodie, I have a box of ten 8" discs that I am trying to sell. They
are single sided, soft sector, single density and are scotch branded.
These discs are VERY expensive now, so make me an offer if you are
interested. They have not been used, apart from one which was formatted
in an IBM displaywriter.

I've already advertised them in cam.misc, so I'm trying further afield.

Talking of discs and linux. I cannot get Archimedes DOS formatted discs to
work properly under linux, they keep chucking up all sorts of errors including
bad MSDOS bread. Seems that RISC OS does not format them 100 percent to MSDOS

why not this way:

============== cut here ==============
#include <stdio.h>

char code[256]; /* or malloc it... */

/* code for this routine will be copied and modified */
 
int sub(int i)
{
  return 69 + i;
}

/* lets go */

int main ()
{
  int (* p) (int i); /* source */
  int (* q) (int i); /* destination */
  char *t; /* used for patch */

  p = sub;
  q = (int (*) (int)) code;

  memcpy (q, p, sizeof(code)); /* copy routine, but no 
                                * more than buffer size
                                * sorry, no way to find
                                * out size of routine.
                                */

  for (t = code; t < code + sizeof(code); t++) {
    if (*t == (char) 69) {

      /*
       * patch the statement adding 69 to one that adds
       * 42. will definitely break with some architectures
       * like alpha and vax were small constants are not
       * stored in a separate byte.
       */

      printf ("found at offset %d\n", t - code);
      *t = 42;
      break;
    }
  }

  /*
   * and demonstrate our new code...
   */

  printf ("q(14) = %d\n", q(14));

  return 0;
}
============== cut here ==============

works fine with Linux, since data segments seem to be 
executable.

to get the necessary prefix and postfix code, do a 

                         'gcc -S filename.c'

of a source containing a stub routine with the
interface you want.

I'm relaying comp.os.linux.announce to Kitsat-A (OSCAR 23) weekly, and
it seems to be warmly received.
Also, I know quite some HAMs running Linux.

Actually, it is not that bad.  But I agree it is not a nice solution.
You could use a FIFO, though...

Yes, but they can't communicate with eachother (yet).
I.e. what you write to ethernet goes out, but is not seen by other
side (Linux kernel or dosemu) on the same machine.

>Can someone suggest an easier way?

Try the FIFO.
If you can program, devise something better, add it to dosemu and submit the
patch to James Maclean.

Maybe its bug free now :-)
The last half year there have been major new releases only after a new
`stable' kernel release:
           1.1.1   .99pl14
           1.1.2   .99pl15
           1.2.0   1.0    
Extrapolating: do not expect a new release before Linux 1.2 comes out.

PPP has more overhead per packet, but this is compensated by larger 
packet sizes.
