SyncTERM is one of the better terminal clients for connecting to a BBS via Telnet or SSH in my opinion, and I have installed it on my Lenovo Thinkpad T440p and my Dell Lattitude running Arch Linux.
It wasn’t difficult to build it from source and install it, but it did require building, not just installing, and therefore I have posted (below) instructions for anyone interested on how to build and install this application from source.
