Hi... Thanks for reply. I know SSCCE.... But I have not code yet. I'm doing some investigation to understand if it is the right way or if twisted has a better standard flow for a similar problem. I will try to write something.... exarkun(a)twistedmatrix.com ha scritto: >On 04:57 pm, s.danzi(a)hawai.it wrote: >>Hi!! >> >>I have to write a little python program to manage a serial port radio >>modem. >>I have to send some AT commands and read resposes.

[Twisted-Python] Help for Twisted + Thread + Message Queue

Hi!! I have to write a little python program to manage a serial port radio modem. I have to send some AT commands and read resposes. This is not a problem, twisted examples are enough. ...but I have a situation that makes things complicated: Anytime the modem can send back to serial port a line starting with "++"... I have to catch it and do some analysis that could take a long time. How to solve???????????????? I have found only this manner: - a thread continuously read from serial port. - if it receive a line stanting with "++" put it in a queue (I could name it "unexpected-queue") - this thread also check for commands on another queue (commands-queue) - if there are something on command-queue it send command to serial port an put replies on another queue (replies-queue) - Another thread loop to check unexpected-queue and do something if there are messages. - main program sent commands to command-queue and read replies from replies-queue Does anyone have better ideas or suggestions?

[Twisted-Python] Conch - Why does one piece of code "fail" while another works
by Donald Stufft 02 Oct '13

02 Oct '13

I have two pieces of code (see: https://gist.github.com/dstufft/9dc9978dc0af77e82f0c) one "works" (in that it fails verifying the host key like i'd expect) and one doesn't ("it never tries to verify the host key and just exists immediately). I don't understand *why* though, why does the connectionReady dance make it work? ----------------- Donald Stufft PGP: 0x6E3CBCE93372DCFA // 7C6B 7C5D 5E2B 6356 A926 F04F 6E3C BCE9 3372 DCFA

[Twisted-Python] raw socket IWriteDescriptor
by David Stainton 01 Oct '13

01 Oct '13

Hi, I'm trying to implement an IWriteDescriptor using raw sockets. So far this is what I wrote... but it doesn't work: https://github.com/david415/hushTCP/blob/master/hush_writer.py Am I doing something obviously wrong here? I certainly am able to use raw socket + scapy correctly without Twisted. Cheers! David
