| | 404 | & KEEPALIVE |
|---|
| | 405 | Flag: KEEPALIVE (players) |
|---|
| | 406 | |
|---|
| | 407 | When this flag is set on a player with a telnet-capable connection, |
|---|
| | 408 | a telnet NOP (no-operation) is sent after there's been no activity |
|---|
| | 409 | on the connection for a minute, to generate socket activity without |
|---|
| | 410 | generating any output. In a way, it's the opposite of the IDLE |
|---|
| | 411 | command. IDLE is sent by clients to keep a connection open, while |
|---|
| | 412 | KEEPALIVE tells the server to send a message. Both are intended for |
|---|
| | 413 | use by people going through home router/NAT appliances with short |
|---|
| | 414 | inactivity timeouts. |
