The packet sequence for the outgoing packet is returned as a result. If the base application has the capability to send on the provided portID. An appropriate absolute timeoutTimestamp must be provided. If the packet is timed out, the channel will be closed. In the case of channel closure, a new channel may be reopened to reconnect to the host chain.

Deprecated: this is a legacy API that is only intended to function correctly in workflows where an underlying application has been set. Prior to to v6.x.x of ibc-go, the controller module was only functional as middleware, with authentication performed by the underlying application. For a full summary of the changes in v6.x.x, please see ADR009. This API will be removed in later releases.
