I now have dosemu 1.1.5.0 with kernel v. 2031 fat 16 as recommended above. It
fixes the lock() problem I was having including file lock() on an Iredir NFS
mounted file system. After some testing, I have found a problem with this
kernel (2031) which occurs both on native freedos boot or using dosemu
1.1.5.0. The problem occurs using stdin input and fgets() calls. They work
one or two times then return junk without waiting for an endline enter
sequence. Here is the function that returns without waiting for the keyboard
enter/end of line:
void chkkbd(void)
{
int ch;
char str[80];
fprintf(stderr, "Hit enter to continue, s to stop, q to quit
immediately...");
fgets(str, 80, stdin);
fputs(str, stderr);
ch = str[0];
if (ch == 's' || ch == 'S') {
bStop = TRUE;
}
if (ch == 'q' || ch == 'Q') {
bQuit = TRUE;
}
}
It is a pretty basic function. I did use getchar() at first, with the same
result. This function works as intended with kernel 1.1.26a (2026a) or in
linux. With kernel 2031 it behaves as described above and if you rerun the
same program it crashes the dosemu session.
Is there an earlier kernel I can use to solve the share/lock issue and not
introduce this stdin problem?
