How to send data on a telephone line to ISO8583 host (Dial up NAC), the client is in JAVA? -
i building iso8583 client written in java, need send iso8583 host hosted on nac dedicated phone number (analog).
the client(pc) generating tcp/ip info , should ideally phone call phone number , send info packets , receive reponse info packets.
i done iso8583 parts , works ip->ip, want know how setup work in ip(tcp) -> analog phone line (host).
thanks, raj
if using nac, don't need tcp -> serial line, job of nac switch unless writing own switch.
the transaction flow goes iso host -> nac (tcp)-> nac (serial) -> terminal/pos.
if want send serial packets pc nac need connect 1 modem serial port of pc , send info across.
if have 3rd party nac (ingenico,verifone) don't need modem give serial interface connect pc send data.
if interested in c apis (you can convert them java), please checkout github project

i suggest fork , create java apis might useful others.
