this post is supplemental to the previous one.

one thing that is causing me confusion when using the niosserial.c driver is the following.

even when i'm not transmitting any characters, and only receiving them, the transmit_chars() routine is being called.

why does this happen? shouldn't this routine only be called when characters are ready to be sent out?

any comments you might have in regards to these last questions will also help me out a lot.

thanks,

not quite sure. Could be Xon/Xoff. You can check what was actually transmitted
