SUMMARY
=======
You can print to alternative auxiliary ports from MS-DOS Editor or QBasic by
saving the file with a file name of the alternative port.
Valid values for parallel ports include LPT1, LPT2, and LPT3. Valid values for
serial ports include COM1, COM2, COM3, and COM4. Other auxiliary devices such as
CON (console) may be used.
The ability to print to any of the above ports is contingent upon the port being
both physically present on the machine and the port being supported by the
computer's system BIOS.
MORE INFORMATION
================
To print to an alternative port, do the following:
1. Open the file you want to print in MS-DOS Editor.
2. From the File menu, choose Save As. You will be prompted for a new file name.
3. For the file name, enter the name of the printer port to which your printer
is attached. A dialog box will appear with the following message:
File already exists. Overwrite?
Select Yes.
The file will then print to the port you have chosen. Saving the file as an
alternative port will not save the file to disk.
