To receive strings from the serial port. Initialize the return string. Dim returnStr As String = ' Determine which serial port should provide the strings. This example assumes it is COM1. Use the My.Computer.Ports.OpenSerialPort method to obtain a reference to the port. For more information, see OpenSerialPort. All ports can be used simultaneously, with the exception of the USB port in ERROR: Variable (USBprogramming) is undefined. For example, a single controller may use one serial port to send messages to a modem via RS232, another port to communicate with a frequency converter, while the controller engages in communications via its CANbus port. String data = sp.ReadLine.Trim ; // (Where sp is the serial port connection). In addition to this, each serial communications device needs an interrupt request number (IRQ) and these numbers are limited in a PC. The end result is that although things look okay, you may still be having trouble with your communication port. On most desktop PCs, you will find two serial (COM) ports. Older systems often have one 9-pin serial.

Hi, I am trying to figure out how to use the serial port in perl. I am using windows with ActivePerl. This is what I have so far: [CODE] $o_rs232Port = new Win32::SerialPort($ARGV[1]) || die 'Can't open $ARGV[1]: $!'; $o_rs232Port->user_msg('ON'); $o_rs232Port->baudrate(115200) || die 'Can't set 115200'; $o_rs232Port->parity('none') || die 'Can't set parity none'; $o_rs232Port->databits(8) || die 'Can't set 8 data bits'; $o_rs232Port->stopbits(1) || die 'Can't set one stopbit';...

I would like to open a serial communications port directly in PB script. I am currently using PB 6.0 and do not see a way to do it without using an .ocx or .dll. I there a way to open a comm port directly in PB and perform simple input/output operations to this port? I have tried without out success to use PDQComm .ocx. I am not sure how to reference the PDQComm.ocx ole object in PB. Plus, I don't have a big budget on this project to buy the 3rd party control. Any help would be appreciated!!

Hi All I am currently using async pro for serial comms, but due to lack of updates/support I would like to move to another comm component. I am currently looking at TComport. In async pro, I bypass the events and send-wait-receive the data. The data sent, is a sequence of integers, sent from an array and received back into an array. Is this possible with TComport or is there a better way? Some code would be appreciated.

What are the options available for PB developers for serial port communication? I browsed the web and found I/O ActiveX Communications Control from JSPayne which is well documented and not that expensive (70$), but takes almost 2M of space (the ocx takes only 48k, other files take the rest) and requires registering during setup. Is there anything smaller out there? Thanks!

Communicating with the serial port
Hi, i would like to know in general how it's possible to communicate with the serial port with Powerbuilder.

Communicate with Serial Port
I am working on a project which is using a digital scale and connect it to a com port. Then using PB to send a command to the scale and the scale would then send back the weight reading to PC. My question is what is the easiest way to do this in powerbuilder. I know in VB I can call open function to open the com port. However, PB is my favour and I don't want to change to VB. I am not familiar with windows API or DLL call. Can anyone help me! Thanks Simon I would guess that Win APIs would be your best bet. perhaps these will help. http://www.vbapi.com/index.html http:...

Hi all, I am able to write to a com port just fine. The problem that I am having is reading from a COM port. Here is what I am doing. I open the com port for write (because I have to send a esc code to the device first). I then issue the ReadFile function. I am not sure if I have the read function defined correctly or if I am calling it correcly. My external Functions are defined as follows: /* To create a file */ function long CreateFileA(ref string lpszName,long fdwAccess,long fdwShareMode, long lpsa, long fdwCreate, long fdwAttrsAndFlags, long hTemplateFile ) library &q...
