If you have PVM, there is a way to set a notification on an attempt to connect to a host. You could also stand up YVETTE, which has a system message screen. You also might ask Rick Troth if he still has the fullscreen PIPE widget he wrote ages ago that used RXLDEV. You could use it to accept the dialed connection, present a nice screen that said "No buses on Thursday" and disconnect.
