User Serial Ports
All Processor module ports except for the port PROGRAMMER/PORT B" on the
leftmost Processor in the rack are available to the user to connect to an external
device. In order for the application software to be able to use a serial port, you
must first use the OPEN statement in a BASIC task. Refer to the Enhanced BASIC
Language Instruction Manual (JĆ3675) for more information. Note that on
AutoMax Processor modules, you can OPEN PORTA" or OPEN PORTB". For
the PC3000 Processor, the number of serial ports available depends on the
setting of Jumper J2.
