Non–Sequence Protocol (ASCII In/Out and PRINT)
Configure the DL260 Port 2 for Non-Sequence
Configuring port 2 on the DL260 for Non–Sequence allows the CPU to use port 2 to either
read or write raw ASCII strings using the ASCII instructions. See the ASCII In/Out
instructions and the PRINT instruction in chapter 5.
