Hello ALL!
In my project i need get some data from user.
I use input command:

INPUT "FIRST DATA", A

and if user not enter data at 5 second i must cancel input and go to main sequence of programm.

How i can do this?
I try use TIMER0 as timer:

Config Timer0 = Timer , Prescale = 1024

and on timer interrupt:

Tim0_isr:
Cycle_count = Cycle_count + 1
If Cycle_count > 100 Then
Cycle_count = 0
Print
Print "Time out - use old setting"
Goto Go2main 'this is goto to main sequence
End If
Return

but something wrong - after some seconds i can enter any data in terminal window and all software - stopped...

Please help.
Sorry my bad english.

Be aware of this:

"The timeout is not in seconds or microseconds, it is a relative number. Only the speed of the oscillator has effect on the duration. And the value of the number of course."

(quoted from BASCOM-help).

2000000 timeout does not nessesarily mean 2 sec!
