my girlfriend will be having a wireless land line..and we are planning to have a dial up internet in their home...we cant afford dsl or broadband because it's costly..now..we're wondering if we can have a dial up connection using that wireless land line..we dont have the manual for that wireless land line...im wondering if that wireless unit can be connected to a 56 kbps modem..

i notice that there's a serial db9F port on the wireless land line..im wondering if that serial port can be connected to the rj 45 of the 56 kbps modem to have an internet since there's a serail rj45 adapter available in the market...is that serial port on the wireless unit for dial up capability?
