|
|
121 // connection. Once the slave accepts the request, then master and slave |
|
|
122 // will execute the operation, typically a test. The control connection |
|
|
123 // will remain active until the master sends a 'disconnect' request. The |
|
|
124 // control connection will be broken after the reply to this request has |
