The application is for uart usage , do you find problem on using uart1?

BTW, you can try my application which is working fine in WP77 and UART1:
UART_TCP_Server.rar (3.7 KB)

AT!MAPUART=17,1
AT!reset
Disable firewall by the following command:
iptables -I INPUT -j ACCEPT
Start the application by
app runProc UART_TCP_Server UART_TCP_Server --exe=uart – 5044 /dev/ttyHSL0 115200
Establish a TCP client connection to 192.168.2.2 on port 5044 through USB ECM interface
Send some data from TCP client and they will be forwarded to module’s UART1
Type some characters on UART1 of module, they will be sent to TCP client.
To disconnect the TCP connection, you can send ”exit”.

Thanks for your great support.
I found the miss port setting by checking your sample application. My code can work fine now.
I will run your application later.
