#20479 - necessary handshake with modem? |
Hi
I am trying to develop a system where a "client"(a 8535) is connecting to a "server"(also a 8535) via modem and through a telephone network. The "server" shall govern the "client" after the connection is made. At the server side a user is able to choose among different datapost(containing a quantity of measure values). The user would also be able to stop the present transmission and ask for another datapost. I will use 9600 in baudrate "all the way"(using AT command to set this value in the modem)client to modem, modem to modem,modem to server and I will use interruptroutine in the software. Software written in C. client->connect send x-values<-server client->x-values . . send y-values<-server client->y-values . . stop and drop<-server connection Problem: In the hardware I want to reduce the connections to save some space. I want to exlude CTS/RTS and DTR/DSR to the microcontroller pins.(Now the they are connected in the serialport, CTS with RTS and DTR with DSR and this works with software handshake). I don“t have access to a tel.net. but I tried this between 8535 and the modem without sending any datapost only some AT-commands. Question: *Withhout loosing any data, is it ok to use the connection over the net without any hardware handshake? *Is there anything else i should think of? Thanks in advance Ann-Sofie |
