What's that? These 2 components are not real PC cards but are more like modems that you use as external device.
Host1-serial - RadioModem1 - - - - - RadioModem2 - serial-Host2
How can I connect it?
If you see them in an abstract vision you can model them like this:
Host1-serial - - NULL MODEM CABLE - - serial-Host2
So you'd have a connection between 2 far serials with 2 possible configurations:
For 1 you can use this simple script in Linux:
"/usr/sbin/pppd -detach lock idle 300 crtscts connect "/usr/sbin/chat -v TIMEOUT 5 AT OK AT OK AT OK AT OK" IPLINUX:IPWINDOWS /dev/ttySx 115200 disconnect "/usr/sbin/chat -v AT OK" ms-dns IPDNS"
The above script is need for letting Windows believe there is a modem on the serial end!
In Windows you need to create a Dial Up connection with crtscts enabled, speed at 115200 and with a stupid number to call (need by Remote Access but absolutely not used).
With 2 Linux boxes you only have to run a very simple script like this at each Linux side:
"/usr/sbin/pppd passive local crtscts IPLINUX1:IPLINUX2 /dev/ttySx 115200 noauth persist"
where you'll invert IPLINUX1 with IPLINUX2 at the other edge.
Note that you can do authentication even Linux-Windows than in Linux-Linux if you want.
