I have tested the program now in the original development PC (a VMWare

physical com port all seems to work OK. In the virtual machine it
means mapping the laptop docking station COM1 into the VM. THen it
works just fine.
But when I involve a USB connected serial port (which I have to do if
I undock my laptop) I get all kinds of strange errors, basically no
communications at all! I have two different ones but both are
problematic (ATEN RS232USB and SUNIX 4-port ComHub).
Do you know of any problems related to SynaSer via USB connected RS232
adapters on Windows7 or WindowsXP?
Right now I am moving the Lazarus application around to different
computers (real and virtual) and different COM ports (real or USB
connected) to try to figure out why it is so hard making it always
work. And this is when I found that I tried ports that were already
reserved for the virtual machine or actually unplugged without
SdpoSerial saying anything about it....
Please test your ports with:

and see if the problem also appears with this application.
