Transfer files between two computer using direct modem connection

[sitrom]

I am developing a data acquisition project on which a file transfer needs to take place. To be more specific i aquire the data and then store them on a txt file. (Up to this point everything is done succesfully). After the above operation is finished i use a mobile phone (connected to a com port) to make a data call to my computer which is on another building and ready to accept incoming calls (set up by windows). After two rings my home computer answers the call and the two computers are connected. Now my problem is that i don't know how to transfer the file from my laptop to my home computer. Any help would be greatly appreciated.

Any other alternatives would be also appreaciated but keeping in mind that the use of the mobile phone is mandatory.Maybe developing an application on my home computer to accept an incoming call or something. Thank you in advance.

Hello,

Assuming that your mobile phone and modem appear as a COM port on both sides of the connection, the XModemSend() and XModemReceive() functions should work well in your application.

More information about a similar application is available in this thread.

Is there any function so that I can use Zmodem instead of Xmodem???

Hi sitrom,

Unfortunately at this time there are no Zmodem transfer functions available in CVI. You may be able to find 3rd party DLLs that will allow you to transfer files using Zmodem. This Google Search might be a good starting point.

Also, you can create a product suggestion for Zmodem support by clicking on the feeback link on this page.

hi

did you ever find a good ZMODEM solution?

There are some DLLs for sale, and I was wondering if you tried any and how well they worked with CVI

thanks
