I want to detect some incoming Characters and act on it. (send other data)

No use of flowcontrol

Iám using the serialterminal program.

Now it seems a problem when I want to send data from the oncom routine.

e.g. when receiving a single character like % I must send directly other data

Also needed string to int and int to string.

cannot find this in help

What is the best to setup such routine for basic4ppc

thanks in advance

Basic4ppc automatically converts numbers and strings.
Using a timer is more foolproof than using the OnCom event.
You need something like:
B4X: 
Sub Timer1_Tick
 If Serial.InBufferCount > 0 Then
  data = Serial.InputString
  if StrIndexOf(data,"%",0) > -1 then '% was sent
   Serial.Output("somestring")
  end if
 end if
End Sub
