| Parameter | Default | Description |
| ------ | -------- | -------- |
| p, port | 33333 | Sender and receiver port |
| f, filename| `none` | Transmitted and received file |
| t, type | receiver | receiver or sender |
| ttl | 15 | Seconds to wait cliend requests or sender responses |
| mtu | 1500 | MTU packet size |

## Script Specification
1. Sender send `NEW_PACKET` packet to broadcast (or unicast) address
2. Sender send all parts of file via `TRANSFER` packet
3. If any pacckets were lost, receiver ask them sending `RESEND` packet to broadcast (or unicast) address
4. Sender wait `RESEND` packets or wait TTL and turns off
5. Receiver ask all lost parts, until the whole file is no downloaded or wait TTL and turns off
