Using system calls

Hi,
I'm new to UNIX system calls. Can someone share your knowledge as to how exactly system calls should be executed?

Can they be typed like commands such as mkdir on the terminal itself? Also, are there any websites which will show me an example of the output to expect when a system call like open() is executed?

Thanks.

NAME
uutry - Tries to contact remote system with debugging on SYNOPSIS
uutry [system] DESCRIPTION
The uutry command is a shell that invokes uucico to call a remote site, system. Debugging is turned on (level 9). The debugging output is put into the file /tmp/system. A tail -f on this file is executed so that the debugging output is printed on the terminal during execu- tion. Typing the Interrupt key sequence gives control back to the terminal while uucico continues to run, putting its output in /tmp/sys- tem. The uutry command overrides any retry period for a remote system and will attempt to establish a connection immediately. The output file, /tmp/system is overwritten each time uutry is executed to system. FILES
On a given system, this file contains a list of remote sites accessible through the UUCP protocol. The primary security file for uucp which specifies access permissions for remote systems. Contains information about devices on the local system that can establish a connec- tion to a remote computer using the uucp program. The spool directory where uucp maintains its temporary work files. Contains lock files that prevent multiple uses of devices and multiple calls to systems. Called the public directory on a given system, UUCP uses it for send- ing and receiving information; ~uucp is a brief way of specifying it. A file created by uutry to contain traces generated by uucico while connecting to system, system. SEE ALSO
