Hello,

I posted a while back about ada packages that aid in serial
programming.  Someone showed me some packages, POSIX_IO, and
POSIX_TERMINAL_FUNCTIONS.

Well, now I get an error when trying to set the baud rate for
some reason.

I open a port and then "Get_terminal_characteristics", use
"Define_Input_Baud_Rate" with POSIX_TERMINAL_FUNCTIONS.B38400
as the baud_rate, and then do a "Set_Terminal_Characteristics".

This gives me an error 22, which is EINVAL (Invalid_Argument).

Is the "Define" function overwriting the TERMINAL_CHARACTERISTICS
structure?  I'd think not since that parameter is a "in out" param.

Any ideas what I may be doing wrong?

Thanks,
Jee
