C d   39

Transmit at least four characters from your system. 

At this point, the printer does not attempt to interpret any printer 
commands, but simply prints each character with its hexadecimal 
equivalent underneath.  

Note: An example of using DOS to verify printer communications 
follows this procedure. 

To enter normal Print mode, turn the printer power off and then on 
again. 

If this procedure does not work, make sure that the DIP switches match 
the serial port configuration of the system and that you have the printer 
cable securely plugged into the correct port of your system. 

If you receive a write fault error, your cabling may not be correct. See 
“Connecting the Printer to Your System” on page 8 for more information. 

Note: Please refer to your host computer user’s manual and the IPL 
Programming Reference Manual for information on downloading
