Under Novell's Unixware 1.1, I am having a problem with a serial device entering
the closing state when I don't want it to.
I am trying to communicate over a long link to a remote terminal. The link will
be RS-485. I am converting RS-232 to RS485, then converting back at the remote
location. I have this mocked up on my desk right now (with a much shorter link
between the converters).
When I just use a null modem, the system works just fine. When I put the RS-485
portion in place of the null modem, the port stops working after the first 12
characters (I think this is more time related than number of characters related
because, if I add a delay after the first few characters, the port will have
already stopped working).
To make matters for interesting, I can use C-Kermit to talk to the port through
the RS-485 link all day without any problem. Obviously, they are doing
something that I'm not; I just can't determine what that is.
Any help, ideas, etc. will be greatly appreciated.
