## What is Glink 3270?

Glink 3270 for iOS is an iOS-version of Gallagher & Robertson's best-selling terminal emulation program, Glink Professional Edition for Microsoft Windows.  

Glink 3270 is used to access applications running on IBM host systems. Glink 3270 emulates all IBM 3270 terminals and uses the TN3270 protocol for communication with the host systems. 

Glink brings you a high quality and proven emulator for your iPad, iPhone devices and Mac computers with M1/M2 chip. 

Glink supports GlinkProxy, a server application designed to provide persistent host connections for Glink clients where the connection from the client device is unreliable. This may be because the device enters sleep mode or goes out of Wi-Fi range.
