sqlcl [ERROR] Failed to construct terminal; falling back to unsupported

sqlcl 18.1.0 [ERROR] Failed to construct terminal; falling back to unsupported

occurs when TERM=xterm-256color.  sqlcl does start, but keystrokes at password prompt are shown as clear text.  If I set TERM=xterm-color it seems to work OK.
