Ugh, I hate the costate begin/stop methods. Mainly because it is so odd
and i am the one that usually ends up porting it to something more
standard. I see this stuff used a lot and it usually ends up a mess a
what normally would be one "task" is scattered in several costates.

Why not just a something simple:

cofunc CoCheckSMS(...)
{
}

cofunc CoFTP(...)
{
}
while(1){

costate {
waitfor(DelaySec(300) && modem_busy = 0);
modem_busy = 1;
wfd CoCheckSMS();
modem_busy = 0;
}

costate{
waitfor(DelaySec(1800) && modem_busy = 0);
modem_busy = 1;
wfd CoFTP();
modem_busy = 0;
}

}

Will be much easier to follow and debug.

I must be missing something about the goal that is to be achieved. If only one of the two functions is to run at any point in time, why are we discussing cofunctions, which are intended to divide time between the two processes?

Perhaps we can simply write a function to see if the RTC minute has changed, and use conventional functions?

while(1)
{
if(newminute())
if(timer1++>=5)
{
CheckSMS();
timer1=0;
}
if(timer2++>=30)
{
UpdateFTP();
timer1=0;
}

}

just a suggestion...

Jon
