You can query the version of the server with the following console command:
===> F SSHD2,VERSION
To check the version of the server in ISPF, enter the Tectia SSH Assistant option 4.1.5 TSRVQV (Query the version of the running SSH server).
You should see the following console messages:
SSZ0003I Command VERSION accepted SSZ0004I Tectia Server for z/OS
<version>SSZ0008I VC branch:

If some of the console messages fail to show up, you can check them in the SDSF log.
