PC— Serial Port

This method for downloading the system software from an IBM or compatible PC should be used only when a parallel port is not available because it’s slower and because it requires a null modem cable (see the “Cable Pinouts” section of appendix B, “Technical Specifica- tions,” for more information) and special software to set the PC’s serial port to 38400 baud (see step 2, below).

After you have decompressed the system software, as described in an earlier section, use the following procedure to update the system software in flash memory.

»Note: If you’re using a parallel port, refer to the previous section, “PC—Parallel Port.”

1Connect the PC to the printer’s serial port, using a null modem cable.

2Download the DOS ModeX program from the QMS Bulletin Board.

Using your modem, dial in to the QMS Bulletin Board, as described in appendix A, “QMS Customer Support.” After you access the QMS Main Library through the L (Library of Files) selection, do the following:

a Choose D (Download a File). b Type hibaud.exe↵

c Exit from the Bulletin Board.
