How to communicate with a USB-232 converter?

[asinro]

hi
I've started R&D work on a USB-232 converter cable (comply with FCC standards).
My application (C++ driver on Linux OS) tries to connect with a device & communicates via this cable.(the device is connected to the rs232 port & PC is connected to the USB port)
I'd tested with the RS232 cable & now I want to use this USB-232 converter cable.
Are there any libraries or sample source codes to do that.
Thanks

Hi,

I had the same kind of problems with windows.
the solution is simple, just install the virtual driver so that it becomes a com-port. and use it like a comport.

some hik ups I had:
- add additional code for checking if the port is still there.
under windows you get "can not open file" error 5.
- if you send small data packets be aware..
do not ask me why but the timing with rs232-usb is bad.
so insert additional time out for responce.
I even had different handling between 2 pc's.
yes, its that bad.

Hope it helps,

Jewe
