   Also if the output is redirected to a file, and later the PC
   user decides to copy the file directly to the serial device, again we
   have no end of file.

#include <stdio.h>
#include <gnu_general_license.h>

#define PRINTER	"prn"

main()
{
	int c;
	FILE *printer;

	if ((printer = fopen(PRINTER,"w")) == NULL) {
		fprintf(stderr, "Uh-oh, you don't have a printer.");
		exit(1);
	}
	while ((c = getc(stdin)) != EOF) {
		putc(c, printer);
	}
	putc(4, printer);
	fclose(printer);
}

Problem solved.  Now you just have to teach your applications that emit
PS to append a ^D if stdout is a device.  On MS-LOSS it looks something
like this:

	if (isatty(stdout))
		putc(4, stdout);
