                          REDIRECT OUTPUT

This option of the MODE command redirects printer port (LPT1: or LPT2: or 
PRN:) output to a communications port (COM1: or COM2: or AUX:). This is useful 
when there is a dot matrix printer on a printer port and a laser printer on
a communications port. [Not supported by OS/2, use SPOOL instead.]

To switch between the two printers, use

    MODE LPT#[:]=COMn:

to redirect printer port output to a communications port, and 

    MODE LPT#[:]

to restore the printer port output to the printer port.

LPT# is LPT1, LPT2 or LPT3, depending on the number of printer ports
    have on the system (probably only one).

COMn is COM1, COM2, COM3, or COM4, depending on which communications port 
    the dot matrix printer is connected to.
