Hello friends,

I would like to ask if there isn't upgrade of the firmware ICD(1) to be able
to program and debug 18F series? I don't need USB port and to pay another
$160 bucks when ICD worked pretty well for my hobby purposes till today.

One more question a little off topic. My next project is to implement ISDN
line instead of two analog to our equipments. I decided to use CMX625 ISDN
TA POTS Interface from CMLmicro (because of delivering). I don't need any
data transmitions - to connect a phones only and to figure time of
connections, to follow D-channel and to control the chip by some PIC.

Where to start to learn anything about ISDN D-channel signaling and/or
protocol? I wasn't able to find anything useable browsing the Internet. I do
know ISDN is obsolete a bit but not here in Europe.

Regards

Igor
