In a message to this list in February this year titled "Lost support
for baud rate of 230400 after minor Cygwin upgrade" Corinna wrote:

: 250000 is not supported and never was.  As I wrote above, B115200 and

: baudrates up to 3000000 (7 digits), which includes 256000, but 250000
: is not amongst them.  It's not a baudrate defined on Linux either.

In the snapshot versions from mid-February there is indeed support for
other non-standard speeds (like 1000000, 2000000, 3000000) in the
tcsetattr() and tcgetattr() functions in fhandler_serial.cc.  There
isn't however the corresponding change to the cfsetospeed() and
cfsetispeed() functions in termios.cc.

Any attempt to set these non-standard speeds with the cfset[oi]speed()
functions will fail unlike on Linux where they will succeed.  The
higher speeds can only be achieved with the tcsetattr() function.

Can the change be applied to the cfset[oi]speed() functions as well
please.
