Re: A new serial baud rate

[henrique <henrique@cyclades.com>]

Hello !!!

After the last e-mails about this issue I've checked the equipment. I am not 
actually dealing with a modem, I'm dealing with a mux/demux which is 
connected to a modem. The demux has 20 ports and 5 of these ports have the
mentioned speed. I have a multi-serial board that uses the UART 16550A.

I plan to make this implementation, firstly using a ioctl as suggested by  
Matti Aarnio, and afterwards changing the termios.h, task that I believe to 
be harder than the first one.

Ed, unfortunately my equipment uses the 2.2.14 kernel. Does your suggestion 
work in such kernel ? It would be the easiest way to solve this.

regards
Henrique
