Path parameters

projectstring required

Project ID for this request.

zonestring required

The name of the zone for this request.

instancestring required

Name of the instance for this request.

Query parameters

portinteger

Specifies which COM or serial port to retrieve data from.

startstring int64

Specifies the starting byte position of the output to return. To start with the first byte of output to the specified port, omit this field or set it to 0.

If the output for that byte position is available, this field matches the start parameter sent with the request. If the amount of serial console output exceeds the size of the buffer (1 MB), the oldest output is discarded and is no longer available. If the requested start position refers to discarded output, the start position is adjusted to the oldest output still available, and the adjusted start position is returned as the start property value.

You can also provide a negative start position, which translates to the most recent number of bytes written to the serial port. For example, -3 is interpreted as the most recent 3 bytes written to the serial console. Note that the negative start is bounded by the retained buffer size, and the returned serial console output will not exceed the max buffer size.

Response

Successful response

contentsstring

[Output Only] The contents of the console output.

kindstring

Output only. [Output Only] Type of the resource. Alwayscompute#serialPortOutput for serial port output.

nextstring int64

[Output Only] The position of the next byte of content, regardless of whether the content exists, following the output returned in the contents property. Use this value in the next request as the start parameter.

selfLinkstring

Output only. [Output Only] Server-defined URL for this resource.

startstring int64

The starting byte position of the output that was returned. This should match the start parameter sent with the request. If the serial console output exceeds the size of the buffer (1 MB), older output is overwritten by newer content. The output start value will indicate the byte position of the output that was returned, which might be different than the start value that was specified in the request.
