Seems like the MVCOM serial port library maybe messing with memory when closing a port. This seems to cause Blitz to lose it...
MRRaven - if your using PB - could you do a simple test that opens a port from Blitz using a PB dll via MVCOM, and another call to close the same port from Blitz. e.g.
PB Code: (compile as PBTest.dll)
ProcedureCDLL OpenPort(PortDef.s)
HCom.l = ComOpen(PortDef,0,1024,1024)
ProcedureReturn HCom
Endprocedure
ProcedureCDLL ClosePort(PortID.l)
ComClose (PortID)
ProcedureReturn 1
EndProcedure
Blitz Decls
.lib "PBTest.dll"
OpenPort%(PortID$)
ClosePort%(PortID%)
Blitz Code
PortID=OpenPort("COM2:4800,N,8,1")
Delay(1000)
ClosePort(HCom)
The 'ClosePort' command will always generate a memory access violation error for me.
Even if HCom is a Global in PB.
