Events in queue ?

[zxcvbn]

I am a new-comer to event-driven progamming. Could someone please tell me what happens in VB when events are fired while an event is being serviced. Are they placed in a queue for servicing when the current event is serviced ?

I notice with interest that MS suggest that event routines for serial communications (MSCOMM) should call a subroutine for the interpretation of received data so that further events are not suppressed. Does this mean that the called subroutine is placed in a queue for processing when the event is serviced, as if it were another event ?

Regards,
