I have big confusion in modules in Symbian layered communication implementation. I think that
PRT modules implements protocols
MTM modules implements messaging
TSY modules implements telephony functionality
CSY modules implements some driver speciific configurations like
IR or serial port configuration..
When I search through EPOC directories I found couple of ".tsy" files like gsmbsc.tsy (implements GSM func?), gprstsy.tsy (GPRS?), hayes.tsy (no idea??), phonetsy.tsy(??). Which module I will use for
a) dialup connection to Internet from emulator
b) connection to Internet through local network
c) connection to Internet through GPRS connection?
I don't think you need a TSY for nay of the things you mention. You only need a TSY if you want your program to make or accept a call. GPRS as far as I know does not require a TSY or CSY for that matter. CSY plugins are used only when you want to access special functionallity of your phone such as IR, Bluetooth or serial port access....
