I am developing a specialised system which uses a satellite phone for
internet access.
The phone itself is buggy and does strange things, and the satellite
connection is even less reliable, dropping the connection after a few
minutes on average.
I am finding that the built-in Windows dialler is not really suitable.
It doesn't properly detect that the connection has been dropped, and
gets itself confused if the connection has not been dropped but the
application is asking for data, and I sometimes get what looks like
multiple instances of the dialler, and then nothing works at all.
Also the satellite provider occassionally fails to complete the DHCP
process, so you get a useless connection (no DNS etc).
I would like to write a custom dialler, which - in the absence of data
- pings some URL say once a minute and if this fails it hangs up and
redials.
How much work is involved in this, or does such a thing exist?
