This is what I use to read data from a medical device:

Code: Select all | Expand


Local cDataRead:=Space( 10 )   //length of data to read
Local cDCB
Local nComm

//Setup COM port
if ! BuildCommDcb( "COM1":9600,n,8,1", @cDcb )
   MsgInfo("
BuildComm Error")
endif
     
if ! SetCommState(  nComm, cDcb )
   MsgInfo("
SetComm Error")
endif

if FlushComm( nComm, 1 ) != 0
   MsgInfo("
FlushComm Error")
endif


//Read the COM port
ReadComm( nComm, @cDataRead )

Standard of communication (via RS232 or sockets) between medical software and medical analysers.

Sorry ... I do not have an example of ASTM.

I simply just read the data on the port and process it. I wasn't even aware there was an actual protocol for RS2332 and medical devices.

Everything I'd tried to solve the problem but to no avail! The only thing I said to use FWH2.7.
I only have a few questions:
- Do I need a library hbcomm.lib? If I need where I can find?
- If your example of you doing, what your opinion may be a reason for me not working?

It could be a problem in your FWH release.

You wrote in your example
favory wrote: if ! SetCommState( cDcb )
MsgStop( "Error SETCOMM!" )
return .f.
endif


Did you correct it to them version? SetCommState( nComm, cDcb )

With version FW1.92 everything works without problems! So the problem is FWH2.7 or xHarbour. Why? I don't know! I have another question. how do I make a simultaneous communication with multiple serial ports?
