>    Affects Versions: 0.12.0

> A connection Open frame is created with the intent of limiting the peer to exactly one link.
> {noformat}
>   pn_transport_set_channel_max(pn_trans, 0);
> {noformat}
> Proton encodes the frame with a null 0x40 going over the wire in the channel-max slot.
> A receiving application treats the value as 'default' and uses the spec default value of 65535. If the receiving application had received a 0x43 (types:encoding uint:uint0) it would have used the intended channel max of 0.
