Create a serial console with "socket (named pipe)" of "/tmp/socket", "from:server, to:virtual machine" in vmware player, etc.. gui. Run the above command after you have booted the guest OS (which should also be configured for serial console).

remserial -d -p 23000 -s "115200 raw" /dev/ttyS0 &

Requires software found at: http://lpccomp.bc.ca/remserial/

Remote [A] (with physical serial port connected to device)

./remserial -d -p 23000 -s "115200 raw" /dev/ttyS0 &

Local [B] (running the program that needs to connect to serial device)

Create a SSH tunnel to the remote server:

ssh -N -L 23000:localhost:23000 user@hostwithphysicalserialport

Use the locally tunnelled port to connect the local virtual serial port to the remote real physical port:

./remserial -d -r localhost -p 23000 -l /dev/remser1 /dev/ptmx &

Example: Running minicom on machine B using serial /dev/remser1 will actually connect you to whatever device is plugged into machine A's serial port /dev/ttyS0.

screen /dev/tty<device> 9600

Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc.

Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this.

Make sure your server's date is correct, otherwise insert your own serial number.

rndc reload

should usually follow this command.

When you need to add another tty device that can automatically start at boot time

stty -F "/dev/ttyUSB0" 9600 ignbrk -brkint -icrnl -imaxbel -opost -onlcr -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke time 5 min 1 line 0

I had a hard time in finding the correct settings to get reasonable output from a coin selector which sends its data over a serial line. In the end, minicom came to the rescue and pointed me on the right track.

So, if you need to do something similar, these settings may help you.

Replace ttyUSB0 with your device file, 9600 with your baud rate, 5 with your read timeout (10ths of a second), and 1 with the minimum numbers of characters you want to read.

You can then open the device file like you are used to do, example:

DATA="`xxd -ps -l 5 \"$DEV\"`"
