Yes, i've the ts-7800 with optionals rs485 driver (i can send data correctly).
I've do some test in this days and i've problems also with a normal rs232 port
(with my
source code and with minicom).
With minicom i receive 2 or 3 character then the system stop to receive data.
I've tested it on ttyS1 (COM2) and on ttts2
Now i'm downloading the latest SD images from embeddedarm ftp site and then
i'll do
other tests.
