"(ii) Each handset has got a RS-232 [sic] serial interface."
Not all handsets have an externally-accessible serial interface - check first before parting with any money! On those that do have an accessible serial interface, it is not necessarily RS232 - see below. "Most mobile outputs TTL logic level voltages for RS-232 signal." In other words, it is not RS232! "There is a complete set of SMS AT command set(that i will send you)" This is defined by ETSI as I mentioned earlier - use the 'Search' on this forum to find the links! The specs are free to download! |
