Reading from a serial device

Hello, I am trying to read from a device that spits out 2 values simultaneously per line when i read from the device through cat /dev/device. These readings are split up by a comma.

Example:
249, 371

165, 398
etc ...

I am programming on a Linux machine and using the read() function. I have never done any serial programming. Is there a flag I can use in the read() function to read until a newline delimiter or the like. If I am on the computer and use the cat command it spits it out perfect, but when I read from the code it only outputs in proper format when I use 1 for the count parameter. I tried multiple values and none of them would give me an output like the examples above. The other way around this was created a loop to read until the comma then store as one value, then read till the newline and store as the second value. Is there a more efficient way to read from my serial device?

Thanks,
Chris

Are you doing this on Windows or Linux or both? Because I've already answered the Linux post, and it would have been good to understand if you need to support multiple platforms - if so, you can't use read(), since there isn't any corresponding function to "tc(g,s)etattr()" function in Windows.

If you have no intention of using Windows, I don't understand the purpose of this post.
