Apologies for the off topic thread, but I'm hoping some of you technical or German (or technical German ) PHers can help.

It takes me about a year to forget that I can never successfully get a dial up connection in Germany, so when I make my annual pilgramage to the hell-hole that is CeBIT I consistently fail to have email access.

Many years ago, a colleague showed me the magic trick necessary to get it to work. Needless to say, this has been forgotton , but it is some kind of modem control command that needs to be used.

So, the problem is that my modem doesn't detect any carrier on the (analogue) phone line; it can be made to dial but nothing is heard back. I have disabled the wait for tone before dialling (so I hear my modem make the call), but nothing is heard in response.

Is there an additional control message I need to send to the modem (or make a modification to the modem initialisation) so that the signalling works correctly? I suspect there is something specific to the analogue signalling used on the telephone systems over there.

Thanks in advance for any assistance, and apologies for the rambling post.

I've had this problem at CeBIT but -- oh dear -- have always solved it by telling the modem not to wait for a dial tone. Same happens in France occasionally too.

Prolly doesn't help much

Try extending the time before dialing using commas before the number. This works for me in France, Germany and Spain.

eg: instead of 08701234567 in the phone number box, enter ,,,,08701234567 - each comma will cause a pause of one second.

HTH, Tony

Thanks for the replies. I tried the delay thing Tony without any success.

Needless to say the telephone I plugged into the same socket using the same cable dialled my ISP immediately with no problem....

Although I'm a 'puter numpty I believe that the fair companies do something to the lines on the stands, you have to have a data line for a modem (and of course pay extra for it) plus a telephone line! WAs like that in Düsseldorf at DRUPA, they'd switched something, but my 'puter knowledge doesn't go that far..... I just had to pay some extortionate rate to get it in..........

I had the problem both with my hotel line and also the lines provided in the press centre, so I think it is potentially a generic problem.

Looking through the '.inf' file for my modem there appear to be a number of different sets of initialisation data depending upon country: I just don't know how to tell the modem driver where I am (or whether it makes any difference).

Jeremy,
I have no idea about analog modems, but
I've found a docu on the net:

General
use country- and area code: yes

Settings
Databits: 8
Parity: none
Stopbits: 1
wait for free line before dialing: yes, only if you are connected to a key telephone system

Some hotels like to hobble the phone lines and then charge you extra to connect a modem. As far as I understand it they use software on the switchboard that detects the modem handshake signal and cuts the line, the exhibition centre could be doing this ?
