Hi,

I’d like to be able to control a RS-232-controlled power outlet (such as [RS232 Controlled Outlet from irblaster.info on Tindie](https://www.tindie.com/products/irblaster/rs232-controlled-outlet/)) from my RV50. Is there any way to send commands to the serial port from Telnet or SSH without having to write an ALEOS AF application?

Hi @msjonker,  
Welcome you to our community!  
According to Software Configuration User Guide for AirLink RV50, RV50 do not support send AT command via RS232 port  
Please refer to Section 11 - Serial Configuration on page 303 in the link below:  
[https://source.sierrawireless.com/resources/airlink/software\_reference\_docs/airlink-rv-series---configuration-guide/#sthash.1Xs56M4U.dpbs](https://source.sierrawireless.com/resources/airlink/software_reference_docs/airlink-rv-series---configuration-guide/#sthash.1Xs56M4U.dpbs)  
You can using a terminal connection (Telnet) or SSH protocol to send AT command  
Please refer to Section 8 - Services Configuration on page 240 in the link below:
