I have only internal modem .....

Probably yes. 1st is 9pin Cannon, 2nd HP-LX specific.

Yes - but see above.

No, because one is Cannon, and second HP-LX specific.

Hmm, so I am more or less where I was.
Another hint: I am using same software as I would use on
normal DOS laptop, ie. intersvr.exe and interlnk.exe.
These tools are designed for "laplink" cable. Is this the
same cable as would be used for connecting one PC to another
as terminal attached to serial port ?
Sorry for my lack of knowledge, but I was never really
experimenting too much with any laptop or notebook, as I
didn't find them too useful - HP-LX palmtop is the first
one that I considered worth to start experimenting.... and
so far I got nowhere. Ok, I can try to borrow external
modem from friend, and see what happens, but I think modem
cables use different connector on the modem end, than on PC
end...
I have to make second half of HP-LX <-> Siemens S35i cell
phone cable myself, and I need to know if it should be
straight cable or cross-connection cable. So far, it is
beyond my imagination... :-(
Laplink is probably crossed cable:
______ _____
PC \/ PC
______/\_____
Now, is the same cable used to connect modems to PC ?
If no, my second cable would probably have to be crossed
again, because cell phone is designed to behave the same
way as modem, so the cable will be probably also the same...
