Open and use a USB serial port just like a regular serial port. How you determine the port number (COMX) depends on the device. There are a few USB serial ports out there. I havs had great luck using TMS Software (www.tmssoftware.com) Asynch 32 under C++Builder 5. Best Buy has one for $29 that works very well. Edgeport has a four port one that works OK also. Saelig (www.saelig.com) has a bunch of 1, 2, 4 and 8 port (great deal at $199US) devices that also work great. Good luck Tom Woodrow www.dacworks.com Rob wrote: > Hello, I have a question about USB comms. > I have C++ builder and at present communicate with some devices using RS232. > I need to swap these over to USB.
