Time to learn the awesome power of Linux.
Three ways to do this:
1. shell script
Create a text file with the following two lines of code:
#!/bin/sh
exec microcom -f -p/dev/ttyUSB4 -s9600
Name it something short and memorable, like serial
Then
chmod a+rx serial
And from then on, it's a program you can run.
2. shell alias
Most shells have aliases available. In bash, you can stick them
in your .bashrc file. Add this line:
alias serial='microcom -f -p/dev/ttyUSB4 -s9600'
and then re-evaluate your .bashrc (which is done automatically
on login):
. .bashrc
Now you have a new command.
3. shell function
Most shells have functions available, too. The difference
between an alias and a function is that an alias is just a
substitution, but a function can take arguments and perform
complicated feats of logic. In this case, a function is
overkill, but it's still easy to drop in to your .bashrc.
function serial {
microcom -f -p/dev/ttyUSB4 -s9600
}
There you go.
