Zack Hi there.

I have a couple of C related questions for you. How can I check to see if my
printer is on line, or even powered on for that matter ?
 I tried the following
 if ( !(status = write(printer, font_code, len) ) ) { print an error message
here ! } but when the printer was off-line, the program stopped until I put it
back on-line.

Also, I was trying to erase just a portion of the text screen by using
putchar(0X04), fflush(stdout), from within a for loop; But the $4 didn't seem
to do anything. These code can be found in the LII manual on page B-3. I also
tried using putchar(0X0B), but that is for a graphics screen. Any clues ?? TC
