Unfortunately my task being locked on the

opened the port with these options
Unfortunately the write call is still indefinetely locking and the
timeout does not seem to apply to writes.

Is there a way to set "control flow" to "none"?
It is possible the hardware is sitting waiting for a handshake signal.

Also have you checked the serial link in any other way, e.g. with Minicom
(or Hyperterminal on Windows)? Or with another terminal (or PC running
Minicom) in the place of "some electronics".

The serial link has been tested using hyperterminal and a windows
application, I am now constructing a linux application using Ada
rather than C sharp which was used for windows. The parity / 8 bit
stuff is definitely ok. I was fishing to see if anyone had used the
serial communications and could confirm it was all working etc or had
a suggestion on why etc. Thanks for your help Brian
