Hi Bryan and thank you for your answer. The solution that you propose me it would be perfect. The problem is where to find a cable to convert USB device to RS232 to connect to the modem.
All the cables that i have found allow:
“The USB-RS232 adaptor cables are a family of communication devices. This cable provides a simple method of adapting legacy serial devices with RS232 interfaces to modern USB ports. ”
And what I need is:
“Connect a USB device to a RS232 modem, where I don’t have a PC and I can not install drivers.”
Does anybody know any adaptor or cable that allow me to connect the USB device to a RS232 modem (MTCBA-G2-EN2)?
Thanks a lot again,
Ignacio
