Question

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.

How can I do this without using Sleep?
Also SetTimer function is triggered in regular intervals.how do i make it trigger at irregular intervals as in the case of my example??
Any help plz.

You can use a Timer

See SetTimer:-
http://msdn.microsoft.com/en-us/library/49313fdf(VS.80).aspx[^]

and OnTimer:-
http://msdn.microsoft.com/en-us/library/fy1hkbdk(VS.80).aspx[^]

This will allow you set durations with a resolution of 1ms (although it will generally not be anywhere near that accurate).

Hope this helps :thumbsup:

When the Timer completes (ie OnTimer) use KillTimer to stop it. :)
