126 CHAPTER 4. THE COMMAND LANGUAGE
tcpdump CIN:n, POS:y, NAT:n
This outputs the list of Cintpos TCP/IP devices that c ur r e ntly exist. The list
includes information about sockets, states and associated hosts and port numbers.
tcprx HOST,PORT CIN:n, POS:y, NAT:n
This is a TCP/IP demonstration program to be used in conjuction with tcptx.
It will output data received from a spe c i fie d host via a specified port. If no host i s
specified wait for a connection from any host. The default port number is 9000.
tcptest -n/K,-k/K,-s/K,-h/K,-t/S CIN:n, POS:y, NAT:n
This is a TCP/IP test program. Se e its source code for details.
tcptx HOST,PORT,N CIN:n, POS:y, NAT:n
This is a TCP/IP test program to be used in conjunction with tcprx. It attempts
to send the message hello world to a specified host via a specifie d port. The number
of times the message is sent is given by the N argument.
testtime CIN:y, POS:y, NAT:y
This command tests the real time clock, outputting a line such as:
days=14876 hours=11 mins=59 secs=11 msecs=982
time TO/K,MSECS/S CIN:y, POS:y, NAT: y
This command outputs the current time of day to the TO file, if specified, otherwise
it is sent to the standard output stream. The MSECS opt i ons causes the time to have
higher precision. Typical output is as follows:
14:12:36.069
type FROM/A,TO,N/S CIN:y, POS:y, NAT:y
This command will output the file given by the FROM argument, sending it to the
screen unless the TO argument is given. The swirch argument N causes line numbers to
be added.
typehex FROM/A,TO/K CIN:y, POS:y, NAT:y
This will convert the file specified by FROM in hexadeci mal and send the result to
the TO file if this argument is given. Its output should be compared with that generated
by the hexdump command.
unhold TASK/N/A CIN:n, POS:y, NAT:n
This Cintpos command resets the HO LD status bit of a speci fie d task. That task
is then immediately available to run unless suspended of other reasons.
unpreload ,,,,,,,,,,ALL/S CIN:y, POS:y, NAT:y
This command will remove up to 10 sp e c i fie d preloaded commands from the Cint-
code memory. The ALL switch will cause all preloaded command s to be removed.
Commands can be preloaded into memory using the preload which can also be used
to list all preloaded commands.
