First of all, sorry for my English.
I'm Windows softphone application developer. The softphone works with numerous USB phones. Calisto P210M was very good USB phone because of it's hardware quality. It was supported by our softphone as raw HID device, as well as the other USB phones. The main inconvenience about P210M was unavailability of detecting key press time, but overall impression of the device was very good.
Now P210M is discontinued and I'm searching for replace. Our company bought P240 (actually they sold us P240-M) and I tried to use it. I've tried to use it as raw HID device, I've tried to use Spokes SDK, I've used it with Skype. I've got some questions:
1. How could I make this phone to send numpad key press events just after key press, without waiting for "Dial" key?
2. Can the phone work with Cyrillic symbols?
Actually I'd like to work with USB phone with no logic, no phone menu (set every pixel of dot-matrix display from PC, receive every key press event for all phone keys, etc.) Almost every prevalent China USB phone works like this, and it's very comfortable for us to work with such phones. However, hardware quality of that phones usually is low, so I'm posting my questions here.
