Stream Switching - (SOLVED)

Hi All,

I have an application where i am using WiFi and a GPRS backup connection.
In a particularly remote scenario I'm faced with, there is no WiFi available so I figured i would just throw in a second GPRS modem each using a different service provider for redundancy. The internet must be available always.

I have developed a driver for a particular modem, of which i have over 20 deployed throughout my city since 2015... it works.

In this case both modems would be identical except for the SIM... i don't feel like loading 2 copies of the same driver is "efficient" if the only hardware difference is the TX/RX pins they are connected to.

Is there a way to simply tell the driver to use a different stream? or am I limited to using a Flag to control which fprintf statement to use on each of the different functions?... this would suck.

Or change which stream corresponds to what UART?
I would like to simply flip a bit and the same single driver now operates on a different UART.

G.

This topic was discussed in the following thread:

Use STREAM 'type' as function parameter.
