Luciano yes. You are right. This is exactly the case. Bruce, sorry, in #13 I did not clearly stated that the device was disconnected.

Please also note that, if all the 3 Hserin commands are joined as one then there is NO problem in the transmitted string! (I do not know if there is other problem in some other subroutine though...)

So, as I can conclude up to this moment, there must be some difficulty from PBP to work with many and some long sub routines.

Also, if the subrounines are transfered from the top to the bottom then this problem disappears! (Others from other sub's are appearing then...)

Black Magic or what?
