5.1. Host Communication Over UART
Host Present NV-item avoids Junk data/false triggers, in case of EVK's where UART1
communication is typically not required.
The Host communication NV-item should be set as 1, to enable the Host communication
over UART1.
The syntax below provides the commands to enable and disable the Host Communication
over UART1
Enable
#setenv hostpresent <<1>>
Disable
#setenv hostpresent <<0>>

Telnet enables bidirectional interactive text-oriented communication with the LS-Platform
Device. Telnet can be used from TCP port 23 (default). The ‘telnet’ NV-item should be set
as 1, to enable the Telnet port.
