I need to different data packets to serial port after specified amounts of time. I can send and receive a single string presently. For example let A, B, C be three strings. First I send A, then after time 'x' I send B, then after time 'y' I send C, after time 'z' I again send A..... and so on.

SetTimer function is triggered in regular intervals.how do i make it trigger at irregular intervals as in the case of my example??

This is just a regular (i.e. periodic) timer with delayed start-up.

I see three options:

if your intervals have a 'reasonable' common divisor then use it to set a regular timer.
In the WM_TIMER message handler kill the timer and then set it again with the proper,different period
Use many (not too many!) timers

Each method has its own drawbacks.
