Hi…

I am porting a few programs from QNX to Linux (go figure), and I wonder
if you know what is the equivalent of Nto’s tcischars in Linux? I need
to know how many bytes are in the serial port so that I can go and read
them.

Thanks…

Miguel

Not sure about a direct equivalent for tcischars, but couldn’t you make
the port non blocking and use select or poll?
