A stateful inspection firewall would typically block the TCP connection entirely or reset it rather than allow a session to open and then return blank or garbled responses to typed commands.

A corrupted telnet service would most likely crash or fail to accept the connection at all, not maintain a stable session that silently swallows commands and returns underscores.

TCP wrappers (via hosts.allow/hosts.deny and the tcpd daemon) intercept inbound connections to services like telnet before handing them to the actual daemon; when configured to block or restrict a client, the wrapper can accept the TCP connection but suppress or distort all output, resulting in the blank screen and garbage responses observed when typing commands.

A honeypot would typically emulate a convincing service with realistic responses to lure and log an attacker; returning only blank spaces and underscores is characteristic of a TCP wrapper restriction, not a honeypot interaction.
