- Fri Nov 21, 2014 6:59 am #3065 I was getting SO excited...

So I took the new webserver example, added a counter - and checked for an argument like www.mysite.com/?myarg=HELLO

Looked up the LUA docs - found the way to do it and


> mycounter=0
> srv=net.createServer(net.TCP)
> srv:listen(80,function(conn)
>> conn:on("receive",function(conn,payload)
>> if string.find(payload,"?myarg=") then
>> mycounter=mycounter+1
>> m="<br/>Value= " .. string.sub(payload,string.find(payload,"?myarg=")+7,string.find(payload,"HTTP")-2)
>> else
>> m=""
>> end
>> conn:send("<h1> Hello, this is Pete's web page.</h1>How are you today.<br/> Count=" .. mycounter .. m)
>> end)
>> conn:on("sent",function(conn) conn:close() end)
>> end)
>



Absolutely GREAT... but ran it a dozen times, the counter worked, the argument came back and then.... I have NO idea why it crashed.

Checked out the examples... despite being able to effortlessly load up the startup routine and other functions, loading the new example telnet crashes the board at different points when I try it - I'm leaving 400ms between sending each line.

Here's what happened with the example Telnet... as you can see - part way through - a reboot.

Same thing happens here, typing incomplete lines in serial.

It is not because of the telnet.lua it-self. Every function with more than 26/27 lines will cause this issue.
You can use file.write to save telnet.lua to flash. and dofile("telnet.lua") to run it for now.

too many (>26) incomplete line input from serial, will reset the unit.
incomplete line means a prompt ">>" shows to wait for another line.
I will debug this.
