SComm64 Communications DLL.
Retrieves the number of bytes in the receive buffer.
MSComm32 and SComm64 have the same syntax and functionality.
value = SComm1.InBufferCount
n = SComm1.InbufferCount
You can not 'Write' any value to this property except 0 (zero) which deletes all data from the receive buffer. Setting any other value causes a trapable error.
