I have two cellphones, and two computers. One computer is a desktop at home with both linux & windows (either), and the other is my laptop running linux. I want to connect the two computers via a voice call over the cellphones.
Has anyone here ever modulated packet data over a phone line? Similar to a modem.
My end-goal is to establish a data connection between two computers over a cellphone link. No GPRS / telco internet provider stuff. No *99# silly business. Just a connection between two computers, over a voice call. I understand the speed will be slow. But that is OK.
I don't have any dial-up modems so I am looking at using ham radio software to send the bleeps over the line. I figure I can wire the soundcard output to the cellphone mic/speaker.
Has anybody experimented with putting PPP over these ham radio thingies? I am extremly ham-noob.
Current things I've tried:
GPSK31 sending and receiving text. This works quite nicely sending beeps out, and receiving beeps too. Not perfect but thats OK.
'hf' and 'hfterm'. I have no idea what I'm doing. I can get text to send/receive with this too. But plaintext only & I have no idea about the options etc.
Questions:
* Is it possible to get the linux pppd program (it starts PPP) to talk to hf, or GPSK31?
* How do you guys get PPP (& ultimately TCP/IP) going over the radio frequencies? And is it possible to switch the transceivers for a telephone/cellphone?
* Am I completely retarded, and doing this the hard way when there is a simple way of doing it? E.g. I can't figure out how to use a cellphone as a -regular- 56k modem. I can dial any number on the cellphone, but not go into data mode to the best of my knowledge.
Specs:
Laptop is the new Asus EEE. I can't find a 56k modem for it to save my life.
Home computer is your typical gaming PC set up, and I have 56k modems & soundcards galore lying around in old dirty PCs.
HALP! HALP help help help help. Thanks
