Figure 6.1.8.1.1 Typical Screen Sections for the SM-RS232 Module

Logical Address

This particular module is accessed over an OS-9 device descriptor and driver which are already present in EPROM on the SMART-BASE. Because the SM-RS232 module can only occupy the first slot on the SMART-BASE, the descriptor is able to access the module directly without the need of a manu- ally entered logical address.

Module Specific Information

dev_file_name : This must be set to scc3

dev_mod_name : This must be set to scc3

hw_handshake : A hardware handshaking flag that is not supported for SMART I/O applications

echo :A boolean flag allowing incoming characters to be echoed to the screen.
