yo.. you probably know more about tcp than i do. is it a robust approach
to assume, that tcp always delivers at least complete or multiples of
if there'd be an easy way to tell when an OSC packet starts and when it
ends, i would do the packet forming on the receiver side myself (in pd).
but it seems, that one needs to parse a lot of the info of the OSC
packet and it seems that it is not so straightforward to do.
actually, because of the same 'you cannot tell how tcp forms packets'
problem, another netpd-server based on [tcpserver] i wrote doesn't work
correctly. because it transports FUDI messages, i can make a
[FUDI_packet_former] by waiting for a 59 10 sequence (;\n) in the stream
to solve the problem. however, this shows, that this problem is not only
related to OSC, but is a general problem of [tcp*]: you have to
serialize lists anyway, so i wonder whether it would be harmful, if
[tcp*] would do it already.
