The IRQ of your serial port hasn't been relevant for about 20 years.
Depending on how your serial port is configured, it may expect RTS/CTS or DTR/DSR handshaking before it will communicate(i.e. will consider the connection 'closed' when certain control lines aren't just right). You can configure this with stty. I think this turns it off.

slattach
SLATTACH(8) BSD System Manager's Manual SLATTACH(8)NAME
slattach -- attach serial lines as network interfaces
SYNOPSIS
slattach [-Hhlmn] [-s baudrate] [-t ldisc] ttyname
DESCRIPTION
slattach is used to assign a tty line to a network interface which uses asynchronous serial lines.
Currently the slattach command is used to attach sl(4) or strip(4) interfaces. These interfaces have to be created using the ifconfig(8)
create subcommand before the slattach command. The network source and destination addresses and other interface parameters are configured
via ifconfig(8).
The following operands are supported by slattach:
-H Turn on DTR/CTS flow control. By default, no flow control is done.
-h Turn on RTS/CTS flow control. By default, no flow control is done.
-l Turn on the CLOCAL flag, making it possible to run SLIP on a cable without modem control signals (e.g. DTR, DSR, DCD).
-m Maintain modem control signals after closing the line. Specifically, this disables HUPCL.
-n Don't detach from invoking tty.
-s baudrate Specifies the speed of the connection. If not specified, the default of 9600 is used.
-t ldisc Specifies the line discipline to use for the tty. Supported line disciplines are ``slip'' (creates a sl(4) instance) and
``strip'' (creates a strip(4) instance). If this option is not specified, the default is ``slip''.
ttyname Specifies the name of the tty device. ttyname should be a string of the form 'ttyXX', or '/dev/ttyXX'.
Only the super-user may attach a network interface.
To detach the interface, use ``ifconfig interface-name down'' after killing off the slattach process. Interface-name is the name that is
shown by netstat(1).
EXAMPLES
slattach ttyh8
slattach -s 4800 /dev/tty01
DIAGNOSTICS
Messages indicating that the specified interface is not configured or created, the requested address is unknown, or that the user is not
privileged but tried to alter an interface's configuration.
SEE ALSO netstat(1), daemon(3), netintro(4), sl(4), strip(4), ifconfig(8), rc(8), sliplogin(8), slstats(8)HISTORY
The slattach command appeared in 4.3BSD.
BUGS
There is no way to specify the interface name (sl%d etc.) to be attached by the slattach command. There is no way to see which interface is
assigned to the specified tty by the slattach command, either.
It would be better if the network interfaces were created by the slattach command rather than by using the ifconfig(8) create subcommand
before the slattach command.
