usage: setserial serial-device -abqvVWz [cmd1 [arg]] ...
setserial -g [-abGv] device1 ...
Available commands: (* = Takes an argument)
(^ = can be preceded by a '^' to turn off the option)
* port set the I/O port
* irq set the interrupt
* uart set UART type (none, 8250, 16450, 16550, 16550A,
16650, 16650V2, 16750, 16850, 16950, 16954)
* baud_base set base baud rate (CLOCK_FREQ / 16)
* divisor set the custom divisor (see spd_custom)
* close_delay set the amount of time (in 1/100 of a
second) that DTR should be kept low
while being closed
* closing_wait set the amount of time (in 1/100 of a
second) that the serial port should wait for
data to be drained while being closed.
^ fourport configure the port as an AST Fourport
autoconfig automatically configure the serial port
^ auto_irq try to determine irq during autoconfiguration
^ skip_test skip UART test during autoconfiguration
^ sak set the break key as the Secure Attention Key
^ session_lockout Lock out callout port across different sessions
^ pgrp_lockout Lock out callout port across different process groups
^ callout_nohup Don't hangup the tty when carrier detect drops
on the callout device
^ split_termios Use separate termios for callout and dailin lines
^ hup_notify Notify a process blocked on opening a dial in line
when a process has finished using a callout
line by returning EAGAIN to the open.
^ low_latency Minimize receive latency at the cost of greater
CPU utilization.
get_multiport Display the multiport configuration
set_multiport Set the multiport configuration
spd_hi use 56kb instead of 38.4kb
spd_vhi use 115kb instead of 38.4kb
spd_shi use 230kb instead of 38.4kb
spd_warp use 460kb instead of 38.4kb
spd_cust use the custom divisor to set the speed at 38.4kb
(baud rate = baud_base / custom_divisor)
spd_normal use 38.4kb when a baud rate of 38.4kb is selected
Use a leading '0x' for hex numbers.
CAUTION: Using an invalid port can lock up your machine!
