it is entirely possible we number the ports
in the opposite fashion to DOS. try eia1.

You can set baud rates, etc., by echoing the right goo into
the ctl file. For example:
echo -n b19200 > /dev/eai0ctl
sets eia0 to 19200 baud. Not all the controls are sticky in
the Unix sense so you should do this while you have the /dev/eia0
open.

When I do this, it just hangs. I'm using a hardware setup (null modem
cable to another machine) which works in DOS.
In another window, 'cat /dev/eia0ctl' returns:
cts dsr ring dcd dtr rts
Is there anything else I need to send to the control port?

This might be a rudimentary question, but
how do I access a serial port?
(for example, to use a window as a terminal)
Thanks,
Andy
