man qemu

Redirect the monitor to host device dev (same devices as the serial
port). The default device is "vc" in graphical mode and "stdio" in
non graphical mode.
search -serial
-serial dev
Redirect the virtual serial port to host character device dev. The
default device is "vc" in graphical mode and "stdio" in non
graphical mode.
This option can be used several times to simulate up to 4 serial
ports.
Use "-serial none" to disable all serial ports.
Available character devices are:
....
"tcp:[host]:port[,server][,nowait][,nodelay]"
The TCP Net Console has two modes of operation. It can send
the serial I/O to a location or wait for a connection from a
location. By default the TCP Net Console is sent to host at
the port. If you use the server option QEMU will wait for a
client socket application to connect to the port before
continuing, unless the "nowait" option was specified. The
"nodelay" option disables the Nagle buffering algorithm. If
host is omitted, 0.0.0.0 is assumed. Only one TCP connection at
a time is accepted. You can use "telnet" to connect to the
corresponding character device.
"Example to send tcp console to 192.168.0.2 port 4444"
-serial tcp:192.168.0.2:4444
"Example to listen and wait on port 4444 for connection"
-serial tcp::4444,server
"Example to not wait and listen on ip 192.168.0.100 port 4444"
-serial tcp:192.168.0.100:4444,server,nowait
"telnet:host:port[,server][,nowait][,nodelay]"
The telnet protocol is used instead of raw tcp sockets. The
options work the same as if you had specified "-serial tcp".
The difference is that the port acts like a telnet server or
client using telnet option negotiation. This will also allow
you to send the MAGIC_SYSRQ sequence if you use a telnet that
supports sending the break sequence. Typically in unix telnet
you do it with Control-] and then type "send break" followed by
pressing the enter key.
I think that it is difficult to get more options that qemu in that
department :-)
Later, Juan.
