How to use console commands and see console output on Minecraft Thermos Server for 1.7.10?

I am using Minecraft 1.7.10 and am running a server using Thermos, a modification that allows me to use both Bukkit plugins and Forge Mods at the same time. My server runs generally perfectly, I can start it, I can connect to it, I can execute commands from in-game. However, while vanilla server comes with a nice UI itself, allowing me to see the console output and use console commands without actually entering the server myself, a Thermos server doesn't seem to. What can I do to fix it?

• I don't think a special "thermos" tag is really needed. There are just 13 questions with the tags "minecraft-server" and "minecraft-modded" together, so I don't think there will be many Thermos questions. – Fabian Röling Apr 24 '18 at 3:48
• There is a Meta discussion going on about the minecraft-thermos tag. Please, don't remove the tag from the question until this discussion gets resolved. It's been 12 days since it was started, the initiative to remove the tag has 1 upvote and two downvotes as of now. – Baskakov_Dmitriy Sep 27 '18 at 2:57

• You could also try just entering that without pause into a regular console. – Fabian Röling Apr 24 '18 at 3:45
