I don't ever recall that happening, but then again I never actually deleted these. I set 'em to "".

I guess it could be something new with Suite 14 that nobody's noticed yet. At any rate, there are other ways to get data from serial ports. You can use the ms comm control or dozens of other activex wrappers, or use the serial api directly. I imagine at some point a serial wrapper will find its way into the .net framework too.

Hi Guys,

Does VEE have a function to inverse, let say an 8 bit binary number?
Eg. 1 (00000001) becomes 128 (10000000)
3 (00000011) becomes 192 (11000000)

Thanks
Kiah Loon

Subject: [vrf] RS232 and linefeed issues

Dear all,

I have come across an annoying issue with using RS232 to collect data. I currently have a work-around but would rather have it work the way itâ€™s suppose to work. I am using VEE 7.52. I have a DUT that transmits 20 bytes of data over the serial port. I have a direct I/O setup to read Binary -> Byte -> Array 1D -> 20 Bytes. This works until one of the bytes coming in is 0x0A. For example: If the 5th byte out of the 20 is 0x0A (linefeed->â€œ
â€ ), and I use the Bus monitor to view whatâ€™s on the serial port, the bus monitor only shows the first 5 bytes coming in and the direct I/O gets a timeout error because it did not get all 20 Bytes. I have gone into Instrument Manager -> Serial Port -> Properties -> Advance settings -> Direct I/O and deleted the â€œ
â€ for Read Terminator and EOL Sequence. But, the direct I/O still keeps any data after a 0x0A from coming through. To get around this, I change the Direct I/O to read one byte and use a forâ€¦loop that calls the Direct I/O 20 times. Is there a way to get the Direct I/O for a serial port to let all data through and not terminate on a linefeed?
