It appears that this is supposed to a DUN modem, because when I try a DUN or HyperTerminal, Blackberry Desktop displays that error message the instant I try to talk to COM6. If someone wanted to make this a TCP/IP link like a USB DSL modem, they would have not used a virtual COM driver, but used a virtual Ethernet/network driver or similiar instead.
I have 22.214.171.124 on my Blackberry but nothing new was installed. I have not installed anything new on my Blackberry other than the stock 126.96.36.199 that's already on my Blackberry. I only installed the virtual COM port driver on the PC side of things.
