The ecosbaud2posixbaud table in termiostty.c is incomplete. The baud
rate entry B1800 is missing.
I have attached a fix.
real_termios_init() is called from termios_lookup() only if the init
flag was not set before.
I could't found where the flag is set. I think it is missing in
real_termios_init?
Because of the flag isn't set, real_termios_init() is called every time
the device is opened and requests the current device baudrate from the
ecos device.
But the value returned from map_ecosbaud_to_posixbaud() could be wrong
because of the missing B1800 entry.
One consequence is that setting a new baud rate could fail after reopen
a device (e.g. current 19200 -> new 38400), because in set_attr () the
new baud rate is only set if it is different from the current one.
nice bug ;-)
