# WHATPORT(211)

## NAME

port 211 — Texas Instruments 914C/G Terminal — Registered to a Texas Instruments 914C/G terminal; museum-grade, never seen live.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA registers port 211 for the Texas Instruments 914C/G Terminal, under both the legacy name `914c/g` and the well-formed replacement `914c-g`. It served a specific TI terminal product and has no specification or implementation in circulation. The entry survives in `/etc/services`, so a scan of an open 211 will print that name with no basis. Identify the real listener; it will be something else entirely.

## EXPOSURE

**Expose with care.** The registered service does not exist in practice, so an open 211 is an unidentified listener.

## CHECK

```sh
nc -vz TARGET 211
```
