Mobile Phones/Laptops

[Guest]

As an Aussie reader this may be a bit late, as I read of the problem in an issue a few months old. Anyway, here goes. To hook a Laptop up to a mobile phone to get on the Internet, the computer must have a serial port. Most mobile phone makers only have data cables going from the phone to a serial plug. Newer laptops have dispensed with serial ports but the phone companies havn't caught up with USB yet.

Next, its's a matter of adding a new modem through Control Panel, using "standard 19000k serial modem" as the new hardware type. You just use your normal ISP dial-up number. BUT, "flow control" must be configured as "Software", not "X on X off". This option is buried in the modem properties. This is all for Windows 95. I could not find "flow control" options in Windows XP. It could be there deep in the menu system however.

You dial up from the computer. My success was with a Toshiba 425CDT, a SeimensM35 and Windows 95 on a GSM network.

Don't forget connection over IR. The Nokia 6210, 6310, 7110, 8210, 8850, 9110 and 9.210 as well as the Ericsson SH888, R320, R380, etc

Moden speed can also be set slightly higher depending on phone & air time supplier.

At present in the UK you can only use Orange, but BT & Voda should follow soon.

Orange offer HSCSD and GPRS for wap & web. the others at present only wap.

For both of the above protocols you should set your speed to 28K.

Other thing to remember is handsets. Fom nokia I know the 9110 & 9210 support HSCSD and probably the 7110, 8210 & 8850 but check.

For GPRS Nokia 6310 and Ericsson T39, R520 and a couple of others. Other manufactures do suply handsets with GPRS and HSCSD capability but as I have had no exposure to them can't help with model names/numbers

I'm not aware of any Laptops that don't have both serial and USB so the serial mobiles should still be OK. As far as flow control goes software and XonXoff are the same thing, as are hardware and CTS/DTS or other variations of hardware flow control.

As per the other reply the IR stuff works well with some of the Windows operating systems but not all. I run W2000 and can't get it to come to life.

Mobile phone manufacturers are really dragging the chain on data developement. Oz manufacturer Voxon are working on some excellent new stuff which will I'm sure be copied by Nokia and Ericsson as usual....

The latest Motorola GSM phones have both USB and RS232 interfaces and work also with GPRS and HSCSD. Ask for V60, V66 or Timeport 280

BT use Panasonic CF27 laptops with built in GSM, expensive, but good kit.
300Mhz / 6 gig / 128m ram.
