    Once again i got ahead of myself. Dial up user phoned in and
    received this error:

    "Error in weather.js api.underground.com returned a
    'querynotfound' error with this description. 'No cities match your
    search query'."
    Do i have the above right?

    That's all correct. I just didn't account for dial-up users. Mainly
    because I don't have any dial-up access, it didn't really dawn on me.

    Can anyone shed some light on how I might test for this scenario? I'm
    guessing the user's IP comes up as undefined in this case?

    Assuming the BBS is using SEXPOTS, the user's IP address should be the IP address of the BBS computer, or possibly 127.0.0.1 (I forget which). You can programatically detect a SEXPOTS/dial-up connection by checking if user.connection is a number (e.g. "28800") rather than a protocol string (e.g. "Telnet").

    Something like this:
    var dialup = (parseInt(user.connection) > 0);

    At least, I think would work (without actually trying it). Let me know how it works for you,

    DM, I was hoping you might be able to help point me in the right direction on this. tbirdsradio had a chance to try out the new version from GitHub that used
    this bit of code (but had no luck):

    var dialup = (parseInt(user.connection) > 0);

    function getQuerySuffix() {
    var qs;
    if (dialup === 'true')
    {
    if (fallback_type == 'nonip') {
    qs = fallback + '.json';
    } else {
    qs = 'autoip.json?geo_ip=' + resolve_ip(system.inet_addr);
    }
    } else if (user.ip_address.search( /(^127\.)|(^192\.168\.)|(^10\.)|(^172\.1[6-9]\.)|(^172\.2[0-9]\.)|(^172\.3[0-1]
    \.)|(^169\.254\.)|(^::1$)|(^[fF][cCdD])/
    ) > -1
    ) {
    if (fallback_type == 'nonip') {
    qs = fallback + '.json';
    } else {
    if (client.protocol === 'Telnet') {
    qs = wstsGetIPAddress();
    } else if (bbs.sys_status&SS_RLOGIN) {
    qs = wsrsGetIPAddress();
    }
    if (typeof qs === 'undefined') qs = resolve_ip(system.inet_addr);
    qs = 'autoip.json?geo_ip=' + qs;
    }
    } else {
    qs = 'autoip.json?geo_ip=' + user.ip_address;
    }
    return qs;
    }

    var wungrndQuery = getQuerySuffix();

    **********

    However, tbird is still seeing an error when the app is launched at Logon and also as a Door/External for his dial-up user.

    DEBUG for weather.js API call looked like this at the time of error: http://api.wunderground.com/api/XXXXXXXXXXXXXXXX/conditions/forecast/astronomy/
    alerts/q/autoip.json?geo_ip=812XXXXXXX

    (Blocked out API and last 7 of phone number).

    Any thoughts as to why I am missing catching this scenario? It's got me boggled
    and I can't really see it.

    Thanks for any help you can lend (and sorry for the long post).

    var dialup = (parseInt(user.connection) > 0);

    However, tbird is still seeing an error when the app is launched at Logon and also as a Door/External for his dial-up user.

    parseInt() is probably the wrong thing for this particular case, because it tries to pull a number out of a string that may contain non-digit characters.

    parseInt('192.168.1.1'); // returns 192
    parseInt('4162737230'); // returns 4162737230

    Assuming that phone numbers will always be strings of digits, you could do:

    if(user.connection.search(/[^\d]/) < 0) {
    // Probably a phone number
    } else {
    // Probably not a phone number
    }

    He's using parseInt() on the user.connection property, which should either be a terminal-protocol string (e.g. "Telnet", "Rlogin", "SSH") or a modem DCE (connect) rate (e.g. "28800"). There should not ever be an IP address or a phone number in the user.connection property.

    Or maybe I missed this other use of parseInt()?

    According to DM, user.connection should return a connection speed for a dialup user (e.g. "28800") rather than a protocol string (e.g. "Telnet"). So the > 0 made sense. I gave it some mock data, and it returned "true" if I fed it 28800, and "false" if I fed it the word Telnet.

    I don't know SEXPOTS (or any dialup to telnet bridge) well enough to know if the Caller ID was going to come back with 10-digit (4162737230), 11-digit (14162737230), +1 format, or even the short 7-digit pattern. So, I was avoiding testing the user.ip_address field even though the phone number was ending up there. I'm not sure if that behavior is predictable across the board. If the sysop had dialup but not Caller ID from thier telco, what does SEXPOTS drop into the user.ip_address? Does it work in Europe? Tricky tricky. :-/

    Quick question, do I have too many "=" when trying to match if "dialup" is "true"? I suddenly thought of it 30 minutes ago. (Maybe go from === to ==)

    Yes - I was wrong, and that makes sense.

    I don't know SEXPOTS (or any dialup to telnet bridge) well enough to know if the Caller ID was going to come back with 10-digit (4162737230), 11-digit (14162737230), +1 format, or even the short 7-digit pattern. So,

    It depends entirely on what caller-ID data the modem gives to the BBS, if any. There may also be international numbers, which would be entirely different. Not worth trying to do a pattern-match, I wouldn't think.

    I was avoiding testing the user.ip_address field even though the phone number was ending up there. I'm not sure if that behavior is predictable

    I think that's where I got confused (I forgot you were using user.connection.)

    across the board. If the sysop had dialup but not Caller ID from thier telco, what does SEXPOTS drop into the user.ip_address? Does it work in

    I think that DM mentioned that the fallback user.ip_address for SEXPOTS connections lacking caller-ID info would be the SEXPOTS proxy's IP address. This won't always be on the local network - in my case, I run SEXPOTS at home, but my BBS is elsewhere.

    could either the caller-ID information (if provided by the modem) or
    the IP address of the SEXPOTS proxy (e.g. 127.0.0.1).

    I started using some mock data (since I don't have dialup to test with). I think I figured this out.

    function getQuerySuffix() {

    if (dialup === 'true')

    ...should be...

    function getQuerySuffix() {
    var qs;
    if (dialup === true)

    This makes it through the function by grabbing the correct fallback lookup.

    Triple Equals works... At some point I tried Double Equals instead (stil works). Should I stick with Triple? I read up on the difference, but not sure if one might be better than the other in this particular case.

    Thank you so much for the help (DM and EC)! More Debug was certainly the difference this time.

    The difference between == and === can be pretty big in some situations. See here for a lot of info:

    But ultimately you can just do this:

    if (dialup) {
    // If dialup is true, then this happens
    } else {
    // Otherwise this happens
    }

    I'd still recommend reading up on == vs. ===, because using both without knowing the difference would probably lead to much confusion.

    var dialup = (parseInt(user.connection) > 0);

    if (dialup === 'true')
    ...should be...
    if (dialup === true)

    That link is incredibly helpful, and I'll read through it more in depth. I appreciate it, thank you! I tested with your suggestion, works like a champ. I'm curious to see tbirdsradio try out the new code.

    I started using some mock data (since I don't have dialup to test with). I think I figured this out.

    function getQuerySuffix() {
    var qs;
    if (dialup === 'true')

    ...should be...

    function getQuerySuffix() {
    var qs;
    if (dialup === true)

    This makes it through the function by grabbing the correct fallback lookup.

    Triple Equals works... At some point I tried Double Equals instead (stil works). Should I stick with Triple? I read up on the difference, but not sure if one might be better than the other in this particular case.

    Isn't the "=== true" redundant? Saying "if (dialup)" should be enough, and it's just as clear as saying "if (dialup === true)", since that has the same meaning.

    Thanks Nightfox, that is what echicken suggested too, and I think I get the concept a bit more now. That is what I ended up using in the code.

    After I hear back on if it fixed the issue with tbirdsradio, who has a dialup user, I'll know if I've covered my bases a bit better now. I'll probably package whats on GitHub right now as the next iteration at that point.

    No, they're different meanings.

    dialup = "Yes"
    if (dialup)
    print("Yessir!")
    if (dialip===true)
    print("Fosho!");

    Would only print "Yessir!".

    Usually, and in the case of this particular script, if(dialup) and if(dialup == true) and if(dialup === true) are all functionally equivalent.

    However, technically if(dialup) is the equivalent of: if(dialup != false), because if dialup = 2, let's say, then if(dialup == true) or if(dialup === true) would not execute the if-block while if(dialup) would still execute the if-block. if(Boolean(dialup) == true) is the equivalent of if(dialup). :-)

    :) Makes sense. I'm still getting to know all the cases of how variables behave in JavaScript. Logically, though, it seemed redundant to check for equivalence to true in an if check. :)

    To expand that... all of the above would == false, but only false would === false.

    Not when testing for equality (and that was the original question). For example: print(2==true), prints 'false'.

    But print('0x01'==true) prints 'true'.

    So here's a super-duper example...
    [1, '1', '0x01', 2, '2', "true", true].forEach(function (x)
    {
    print("X="+x+' '+(typeof x));
    if (x)
    print("Is");
    if (x==true)
    print("True");
    if (x===true)
    print("Truth");
    print('');
    });

    Which results in:
    X=1 number
    Is
    True

    X=1 string
    Is
    True

    X=0x01 string
    Is
    True

    X=2 number
    Is

    X=2 string
    Is

    X=true string
    Is

    X=true boolean
    Is
    True
    Truth
