I have to write a data acquisition system mostly in Visual Basic - and
some questions;)

1.) Is it principle possible to write this program _completly_ in VB?
(concerning the serial communication - the baud rate goes up to 57.6
kbit/s!) Or do I have to use some self written or third party tools for
this task?
2.) I just make some ?first steps with MsComm.Vbx. Is this the
appropriate tool?
3.) What about garbage collection and other time consuming events? Do I
have to bother about that using MsComm.Vbx?
4.) Where can I find some code snippets ore example source code?

5.) How can I handle the control of the selected com-device, especially
if another program using it is running? (e. g. MS-Exchange) (This is
only a academically question, because the serial port will be dedicated
in this system)

Thanks very much for your answers...
