have a GSM digital phone, on a Cellnet tariff with SMS capability. Cellnet tell
me that I can only send and receive SMS text messages to and from other Cellnet
phones, using their message centre. Is there any way to send message to GSM
phones on other tariffs?
from your mobile phone, and not in the UK. You can only send messages to other
digital cellphones on other networks by going through their own message
centres, or by using PC SMS communications software packages like Mobile
Messenger and PageMail. Inter-network SMS messaging is only possible when both
users are abroad ‘roaming’, on the same network. Cellnet currently share around
80 networks with Vodaphone world-wide. Orange mobile phones work in around 28
countries. Unfortunately as far as we’re aware no-one has yet sat down and
worked which of the shared networks are data compatible.
your procedure for selectively removing file names from the Document list on
the Start up menu (F!F!F! 09/09/97). I use Windows 95 and have tried to follow
your instructions but can't locate any file called Recent in the Windows or any
omitted to say that Recent is a ‘hidden file’ that only appears in the Windows
95 folder when the ‘show all files’ option has been checked. If you’re in
Explorer you will find it in Options, which is under View on the toolbar.
wonder if the questioner, asking about password protection (F!F!F! 02/09/97), was
referring to the Windows 95 password option. To restore the function -- if it
wasn’t selected after installation -- open control panel and double click the
password icon. Select the ‘Users can customize’ checkbox, click OK and restart
Windows. Open control panel and double click the password icon again. Change
the password with the change password option, leaving the old password box
the Window 95 password protection is next to useless. It only safeguards
user-set preferences, it certainly cannot prevent Windows from booting up;
simply pressing the escape key will override it. The only sure way to prevent
unauthorised use, is a third-party
program, such as Norton’s For your Eye’s Only, which provides a high level of
protection, for both programs and files.
know this might seem like an elementary question, but with regards to the
equipment you mention, i.e. scanners, Zip Drives etc., do these items involve
the installation of cards apart from the software? To which port is the
majority of budget and mid-range flatbed scanners use a SCSI (small computer
system interface) card, known as ‘scuzzy’ to it’s friends, and enemies... The
card plugs into a spare ISA expansion socket inside the machine. Some recent
models now come with PCI SCSI cards, which improve performance dramatically. A
few scanners connect to the PC’s parallel printer port; they have a by-pass
connection, so the printer can remain connected. Zip Drives are available with
parallel port or SCSI card interfaces. Faster, higher capacity external drives
like the Iomega Jazz are usually SCSI only. Devices like digital video cameras
generally connect to one of the PC’s serial ports.
have been offered a 386 PC with Windows 95; will the 386 accept Windows 98,
when that is released? What is a fair price for a well-used 386? My computer
literate neighbour suggest it is virtually worthless.
D. More, Newmarket, Suffolk
95 only just about runs on a fast 386 with at lots of RAM memory, and then very
slowly. It’s highly unlikely the next version of Windows will have anything to
do with older, pre-Pentium machines. Old PCs are certainly not worthless, there
are plenty of 386’s and even 286-based machines still earning their keep. A 386
under Windows 3.1 can run useful applications like Word 6 and internet software
without any problems. As far as value is concerned, you can still pick up
‘as-new’ 386 systems advertised for
less than £150 in magazines like Micro Mart. On that basis a ‘well-used’
example probably isn’t worth more than £75 to £100, say, assuming that it is at
least a 33MHz processor with 8Mb of RAM, 100Mb or larger hard disc and a decent
the letter from Bernard Tate about lightning damage to PCs and peripherals,
(F!F!F! 26/08/97), I believe this problem is a lot more common than you may
believe. Lightning doesn't need to strike a substation or power cable directly
to generate a transient over-voltage or 'spike'. Most are the side-effects of a
strike elsewhere and can affect computers up to a kilometre away.
in the UK is surprisingly frequent with up to 500,000 strikes annually, this
year is shaping up for a record. Whilst it is correct to say that BTs phone
network is safeguarded from lightning, the measures taken at PBXs and your own
socket at home provide little protection. In Bernards case it sounds like a
transient on the phone line was responsible and he was lucky the only damage
was to his modem.
by the response to this query it does appear that damage to PCs and modems due
to lightning strike is not at all uncommon. The best advice seems to be to
unplug both the pieces of equipment and disconnect the modem from the phone
socket, until the storm has passed well clear.
