It looks like I might have jumped the gun just a bit. The VX-4500 reports an OK status following AT+CRC=1, but does not (so far as I can tell) report incoming voice calls. I've been looking for another associated parameter that might be affecting this, but can't find one. As a result, there may be no notification. Others might want to try on their CDMA phones to see if they get different results.
On the up side however, the answer string does definately work. As a result, I'd like to know if there's a way to activate the call button to issue AT$QCCAV during those times when it's not set to dial out (which only seems to occur when the dial pad is active AND has numbers entered).
If Zorro can add this functionality, most CDMA phones should be able to:
1. Dial out.
2. Answer incoming phone calls. (Perhaps MediaPlayer volume can be muted during a manual answer (instead of ring), and unmuted during hangup).
3. Import their phonebooks into Phone Control. (I first transferred my phonebook into Verizon's Mobile Office utility. From there exported the file, and then easily imported into Phone Control using PBConvert. BitPim is another alternative.)
You likely won't be able to:
1. Transfer SMS messages.
2. Transfer the phonebook directly into phonecontrol.
I would also encourage those using Nokia CDMA phones to try all features, because it appears as though they might include the full GSM command set.
In further testing, I was also able to get PhoneControl to communicate at 115200 bps, which is the maximum speed that the USB->Serial adaptor can be configured for. It should be noted that the phone defaults to 230400 bps.
Thanks again for everything Zorro,
PS - Perhaps anyone who has a PBConvert template that works for a particular phone/software configuration should send it to Zorro (if he wouldn't mind ) so it can be available to others.
