Adds an interface with a direct TCP/IP socket connection to a Cortex CRT modem at a specified IP address.

```csh
csp add cortex_crt <ip_address>
```

--------------------------------

### Set Default Node

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/command_examples.rst

Sets the default or environment node for most commands. Providing the node as a positional argument when running a command overrides this default.

```csh
node 6
```

--------------------------------

### Add Leafspace MQTT Interface

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/cortex_examples.rst

```csh
csp add leafspace -u <user> -w <pass> 589 25667 mqtt.leaf.space
```

--------------------------------

### Add Remote Parameter to List

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/command_examples.rst

Adds a remote parameter to a list without downloading it from the device. This command requires specifying the parameter name, type, and value.

```csh
host>6> list add -c "FRAM+C" -m "Rt" hk_next_timestamp 154 uint32
```

--------------------------------

### Request Interface Statistics

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/command_examples.rst

Remotely requests interface statistics for a specified interface, such as CAN0. For a combined overview, use the 'csp_print_cnf' parameter.

```csh

Environment variables can be used within other commands by enclosing their names in $(...). This allows for dynamic command execution based on stored values.

```csh
watch -n 5 ping $(MY_VARIABLE)
```

--------------------------------

### Set a Single Parameter on Remote Node

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/command_examples.rst

```csh
host>6> set gndwdt 10000
   | 1:6  gndwdt               = 10000 uint32[1]
```

--------------------------------

### Ping a Remote Node

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/command_examples.rst

Sends a ping request to a remote node and waits for a reply. This is useful for checking network connectivity.

```

--------------------------------

### Reboot a Remote Node

Source: https://github.com/spaceinventor/csh/blob/master/doc/MAN/Operating_Instructions/command_examples.rst

host>> power off obc
```
