serial port data acquisition without data loss?

Post by Jim Part » Wed, 02 Aug 1995 04:00:00


A group in my lab wants to write a data acquisition program running under
Linux with a Tk/Tcl interface. The data will be coming in the serial port
at 19.2 kbps, and we need to ensure that there won't be any data lost,
no matter what else the user is doing. Can this be done under Linux? If so,
how? Is it already taken care of with hardware interrupts for the serial port,
so that it is read out before its 16 byte buffer starts being overwritten?
Does the process need to have its priority put at an especially high level?

Thanks very much. Sorry if these are stupid questions.
