[[Image:RS232_illu_p11.jpg|400px]]
Normally, printer output is sent to the parallel Centronics port at the rear of your computer. Having connected and set up the RS232C, the following commands will cause all printer output to be sent via the serial interface:
AMSTRAD BASIC: '''|SERIAL'''
CP/M 2.2: '''STAT LST:=TTY:'''
CP/M Plus: '''DEVICE LST:=SIO'''
When operating with CP/M, it is possible to program this re-direction as part of the loading process. For CP/M Plus, you should incorporate the command given above into the ‘'''PROFILE.SUB'''‘ file. For CP/M 2.2, you should use '''SETUP.COM''' as described in Appendix 2.
