"Write" - how to quit by press enter

I need to make Bash script. It has one parameter - user ID. If this user is online you can write him a message with "write" program, but only one line. After pressing ENTER "write" program should quit. Normally when you run "write" you can write next line after pressing ENTER and you can quit "write" with ctrld+d. What possibilities I have?

How can I send variable with "write"?
