We have used this filter when printing a file from a PC to postscript
printer on a ultrix machine. 


/* This is a simple filter, which puts carriage returns (13 dec, 015 oct, */
/*  0xD hex) before each new line (line feed = 10 dec, 012 oct, 0xA hex)  */
/*  and after control-d ( 4 dec) and strips any possible control-z's (DOS */
/*  end-of-file marks) off                                                                                                                        */

#include <stdio.h>

main(argc, argv)
int argc;
char *argv[];
{
        register int c;      /* incoming char */

        while ((c=getchar()) != EOF) {
                if(c == 26) continue; /* control-z */
                if(c == 4) {          /* control-d */
                        puts("\004\r");
                        continue;
