If you have an M300 Workstation and a serial printer, you may have noticed that WordStar version 3.3 will not print through the COM2 port even after you have issued the appropriate MODE commands. The reason for this is that WordStar bypasses DOS for printing, preferring to handle printing on its own. Unfortunately, WordStar assumes that a serial printer is connected to COM1. If your serial printer is on COM2, you may want to make the following modification patch to WordStar. This patch changes the serial printer port from COM1 to COM2.
