Netsend outgoing Port number?
by David Sabine 02 Oct '02

02 Oct '02

Hello all, I'm using PD within an intranet (I've got 3 computers networked using a D-Link 704 Ethernet gateway/router) and I'm having trouble using netsend and netreceive in this environment. It looks like I need to configure the D-Link manually to allow communication on specific ports - it has a built-in firewall. For example: I've manually configured the D-Link to allow incoming messages to Port 21 for FTP services on my server and port 80 for WWW messages, etc. I can configure the D-Link to 'listen' on any port I want, but only if there's an outgoing message that corresponds to the incoming port. For example, if a message goes out of PD on port 3000, then the firewall allows a response from an external computer on the same port. The D-Link interface calls this a 'trigger'. Hence, if PD's netsend (for TCP) uses port 200 for all outgoing message, then I can tell the D-Link to open ports 2999-49999 for incoming messages. So the question is: Which port does [netsend] use for outgoing messages? many thanks.. Dave Sabine

RE: [PD] -asio startup flags
by Wakefield Graham 01 Oct '02

01 Oct '02

Hi, Firstly, apologies to the list to send such a dull first message; I'm really enjoying getting my teeth into PD, but I'm suffering some rather unlikely latencies from my soundcard & I wondered if there was any better explanations of the startup flags that the ones in the Doc (chapter 3). I'm using an Edirol UA-100 on a Sony Vaio on win98SE, and the soundcard provides 3 ASIO drivers (native, MME & DirectSound); using another application (AudioMulch) with the native ASIO driver I can get a workable latency of 34ms by specifying 3 buffers of 2048 bytes each. Using the PD starting up -asio -audiodev X (for the native driver) I get a latency of 730ms!! Dropping -audiobuf below 50 causes stuttering of the audio, but while I can get -blocksize down to about 16 it doesn't affect latency. I don't understand what -frags or -sleeptime or -rt do, or how to use them, but I wonder if they may help? I've tried the other ASIO drivers of the soundcard, but they either do not permit full-duplex, or cause cpu overload. Could anyone offer any guidance as to the other flag settings, and if there is any way I could specify the number and size of buffers as I have in AudioMulch? Many thanks, Graham
