All good feedback. If it matters I am using Debian Sarge 10/27/05 off the CF
card and my
board is a TS7200
I had checked the file /usr/include/termios.h which uses
/usr/include/bits/termios.h
where B19200 is defined. It is defined as "#define B19200 0000016" which
matches
neither value printed.
Also I used "stty -F /dev/ttyAM1 speed 19200" on the command line prior to
running the
application as stated and both in and out should have the same speed of 19200.
Yet
different values are printed and neither agrees with the declared value. I
believe the in and
out speeds are actually 19200 as the read function outputs data exactly as
expected.
I also get errors in the routine that would set the data but I am focusing on
the read
configuration function as both issues are likely related and it is the simpler
routine.
Thanks for the help and suggestions so far
