Hi, Another follow-up question. I managed to install both the emulator and the virtual null modem.
Basically, I created a virtual COM5, with 2400,8,N,1, and I set it to transmit a string of "as=ale=0023.82(kg)aksj" every second. Then, I created a virtual null modem to connect COM5 to COM3, no handshaking, with COM5 use enable interference, and about 50% of the bar (I tried 0% - 100%, no difference).
After that, I use hyperterminal to try to capture the data.
The thing is, the transmitted data and received data are different:
- Log from the emulator: S: ===> Text data begin <=== <-as=ale=0023.82(kg)aksj S: ===> Text data begin <=== <-as=ale=0023.82(kg)aksj S: ===> Text data begin <=== <-as=ale=0023.82(kg)aksj
- Captured data from Hyperterminal: aÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁÁaZZZZZZZZZZZZZZZZZZZZZZZa>>>>>>>>>>>>> >>>>>>>>>>a####################### => here, all received data are 24 chars, and started with the letter a.
Anything I did wrong?
Please help.

Hi,
Sorry, newbie question.
I'm building a text parser for my scale. However, the location of the scale is on remote position, and there is no internet available. So, i'm trying to emulate a COM port (my laptop doesn't have serial port) to transmit a certain string data, and the the data is to be captured into my VB application.
Can I do that using the COM port emulator? If so, how? When I start the emulator, my VB app is unable to open/use the port object, where it said that the port is already opened.
Please help.
Regards, :rherry
