Aha, thanks for an explanation!
Now I've started to understand what is this all about. :)
Lets add dosemu-devel and Eric Biederman into CC.
The beginning is here:

Sure: in pktnew.c please find the following:
        if (write(pkt_fd, SEG_ADR((char *), ds, si), LWORD(ecx)) >= 0) {
                    pd_printf("Write to net was ok\n");
                    return 1;

and the following:
    size = read(fd, pkt_buf, PKT_BUF_SIZE);
    if (size < 0) {
        p_stats->errors_in++;           /* select() somehow lied */
        return 0;

and that's it. :)
