Cannot you use alarm_isr() to increment a variable each second,

Then have main set a flag that resets the counter in alarm_isr()
before it reaches 5 if data comes in?

Then when mai nsees the flag that 5 is reached (in your main loop),
it should do something.

If I'm using alarm() to count seconds, then the read() would only
be able to check for incoming data every second, no? I think I'd
lose a lot of data that way.
