I have a program that does serial communications.  I have gotten
requests to support speeds above 19.2kb.

serial.h shows the following speeds defines (divisors) sent to
serial chip:

#define baud300 380
#define baud600 189
#define baud1200 94
#define baud1800 62
#define baud2400 46
#define baud3600 30
#define baud4800 22
#define baud7200 14
#define baud9600 10
#define baud19200 4
#define baud57600 0

It looks like baud38400 should be 2 but I have not been able to get
the driver to respond to 384kb.  I have tried 1, 2, and 3 as the
divisor.

Has anyone got the serial driver to run at 38400kb?  If so how?

Thanks for your help in advance.
