I am working on a serial line transfer program which essentially
reads a character, puts a character, etc. I am having a problem
with the terminal control parameters.

Using emt, I can see the data on the screen, and I noticed the following:

        With TCTL set to -default, the node should be sending ctrl-s and ctrl-q,
        right? However, the node doesn't, and in emt I can manually send ctrl-s
        to stop the data from coming, and ctrl-q to restart the data. Because of
        this, I get continuous character framing errors.

What are the TCTL settings which allow the computer to automatically handshake?
It seems according to the tctl help file that the default setting (-sync) should
take care of it, but it doesn't.

Thanks to anyone who can help.
