DIO_TCSETATTR(3) 1 DIO_TCSETATTR(3)dio_tcsetattr - Sets terminal attributes and baud rate for a serial portSYNOPSIS
bool dio_tcsetattr (resource $fd, array $options)
DESCRIPTION dio_tcsetattr(3) sets the terminal attributes and baud rate of the open $fd.
PARAMETERS
o $fd
- The file descriptor returned by dio_open(3).
o $options
- The currently available options are:
o 'baud' - baud rate of the port - can be 38400,19200,9600,4800,2400,1800, 1200,600,300,200,150,134,110,75 or 50, default
value is 9600.
o 'bits' - data bits - can be 8,7,6 or 5. Default value is 8.
o 'stop' - stop bits - can be 1 or 2. Default value is 1.
o 'parity' - can be 0,1 or 2. Default value is 0.
RETURN VALUES
No value is returned.
EXAMPLES
Example #1
Setting the baud rate on a serial port
<?php
$fd = dio_open('/dev/ttyS0', O_RDWR | O_NOCTTY | O_NONBLOCK);
dio_fcntl($fd, F_SETFL, O_SYNC);
dio_tcsetattr($fd, array(
'baud' => 9600,
'bits' => 8,
'stop' => 1,
'parity' => 0
));
while (1) {
$data = dio_read($fd, 256);
if ($data) {
echo $data;
}

ttysrv - connect to a serial port and log output
SYNOPSIS
ttysrv [-o option] [-s sock] [-l log] -t tty [-b baud] [-p parity] [-w wordsize] [-i pidfile]
DESCRIPTION
ttysrv is the backend for rconsole. It connects to the serial port, handles the log file and waits for connections from rconsole to view
what's happening on the serial console.
OPTIONS -t tty Specify which device to connect to.
-s sock
The name of the socket to listen for connections from rconsole on.
-o option
Specify any ttyios options to open the port with. Currently only nolocal is supported.
-l log The logfile to write to. If not set then no log is kept.
-b baud
Set the baud rate to talk to the port at. Defaults to 9600.
-p parity
Set the parity for the serial port. Defaults to none.
-w wordsize
Set the word size for the serial port. Defaults to 8 bits.
-i pidfile
The file to write the pid of ttysrv to. If not specified no such file is written.
SEE ALSO rconsole(1), remote-tty(1).

I'm stuck here trying to connect to a 280R via serial port A to a laptop. I set hyperterminal up for 9600, 8, N, 1, but when I hit enter, nothing comes up in hyperterminal. There is no keyboard or mouse attached to the 280R, and it doesnt have a video card, so thats not an option.

I have a USB serial adapter that supports arbitrary baud rates. To set a nonstandard rate in code, I'd been using the TIOCGSERIAL like so:
struct serial_struct ser_info;
ioctl(ser_dev, TIOCGSERIAL, &ser_info);
ser_info.flags = ASYNC_SPD_CUST | ASYNC_LOW_LATENCY;
