A Processor Adapter cannot support more than one stop bit. If you change this 
default setting in the configuration software, the Processor Adapter will ignore the

software. 
Auto-Logout 
Feature
If a programming panel is logged into the CPU via the RS232 serial port and its 
cable gets disconnected, the CPU automatically logs out the port. This auto-logout 
feature is designed to prevent a lock-up situation that could prevent other host 
stations from logging in on other ports.
