Of course I can send it only when I get next pulse, which might happen much later. However, the in-kernel decoders depend on the last space to be sent right away. that it I need to and a keypress with a space, but currently it ends with pulse. So my idea was to wait reasonable time for next pulse, and if it doesn't arrive, send a space mark even though no new pulse is registered. Of course the size of that space can be configured.
