Version 1.6 Commands: 7-May-84
com -- switch to communications mode
cb -- switch to communications mode, with windowing to make
usage in CB pleasant. (Note you must be in half duplex
mode to use this effectively).
exit -- return to DOS
set -- Manipulate function key assignments
set -- list the current assignments
set key string -- make an assignment. E.g.:
set f1 "ls"
Note that function keys are called f1 ... f10, shifted
are called s1 ... s10, alted a1 ... a10.
stty -- set terminal parameters:
stty <nn> -- run at <nn> baud (e.g., 300, 1200, etc.)
stty 80 -- Switch to 80 column B&W
stty 40 -- Switch to 40 column B&W
stty w -- accept VIDTEX switch to wide character
stty -w -- screw that, I didn't buy this computer
to make it look like an apple
stty v -- Treat ESC I as a vidtex poll sequence even
when the idiots forgot to sen the SI first
stty -v -- Do as a VT52 with a ESC I unless in protcol
mode (idiotic people at CIS...mutter curse)
stty f -- doesn't work yet
stty -f -- I told you so.
stty echo -- Remote echo
stty -echo -- Local echo

stty 8 -- Allow 8 bit (graphics) characters
stty 1 -- Use only screen 0 (monochrome/Tandy 2000)
stty 4 -- Use all 4 screens (IBM/CGA)
cat -- aka type to non-UNIX fans:
cat <file> -- print out the contents of <file>
switch <n> -- switch to screen <n>
clear -- clear the screen
cap -- menu based capture buffer control
xmodem -- Perform an XMODEM style file transfer
xmodem -rt <file> -- receive a text file into <file>
xmodem -rb <file> -- receive a binary file into <file>
xmodem -s <file> -- transmit a file named <file>
sendf -- send a file, no error checking protocol
sendf <file> -- sends the file without linefeeds
sendf -l <file> -- sends linefeeds and all
ls <drive> -- shows the files on [optionally] specified drive
more <file> -- similar to type, but pauses every so often so you don't
feel like it's a speed reading course. <space> gets
you one more line, <return> another screen full.
dial -- Do funny things to the phone:
dial -- prints a list of known #s
dial <name> -- place a local call to <name>
dial <name> <car> -- place a long distance call to
computer <name> using the long
distance service <car>
ap <file1> <file2> -- append file1 to file2
apl <file> <text> -- Appends the line of <text> to the end of <file>
cp <file1> <file2> -- copies file1 to file2
grep <pat> <file> -- Print all lines in file <file> with <pat> in them
mv <file1> <file2> -- Renames file1 to file2
rm <files> -- Deletes the specified files. rm will happily get
rid of everything if you rm *.* <caveat>
sleep <time> -- sleep <time> seconds. Used primarily for waiting
for the Hayes to let you talk to the world after
it says "CONNECT".
send "<message>" -- transmits <message> to the modem (or whomever is
listening to the modem, eg., CIS). Note that
"\m" is control-m, "\c" is control-c, ... etc.
wait -- waits one of several patterns to appear in the
stream of data from the modem.
open -- opens the capture buffer
close -- closes the capture buffer
write <file> -- appends the contents of the capture buffer to the
end of the specified file.
echo <text> -- prints <text> out on the screen
misfort -- Used to generate and transmit "fortunes"
(details TK)
wc <file> -- compute number of chars, words, and lines in <file>
read <var> -- reads one line of text from terminal into variable
pwd -- prints the current directory (DOS 2.0)
cd <path> -- change directory (use of "/" instead of "\" is OK)
pattern -- Define the patterns being watched for in the
stream of text from the modem:
pattern reset -- reset all patterns to inactive
pattern reset n -- resets pattern n (0..9) to inactive
pattern n "pattern" -- defines pattern n to match contents
of quotes Note that \m is etc.
if -- Conditional branch:
if match n <label> -- if the wait terminated because
pattern n was seen, goto <label>
if !match n <label> -- if ... any but pattern n ...
if same <a> <b> <label> -- If a==b, goto label
if !same <a> <b> <label> -- if a!=b, goto label
if !fexist <file> <label> -- if <file> doesn't exist...
goto <label> -- Unconditional branch
: <label> -- Branch target. Must have *exatcly* one space between colon
and <label>. Also useful for comments.
<name> -- Invokes a "script" of commands. If there is a file called
<name>.csh, it will be used for commands. Nesting up to
five levels permited.
Multiple commands on the same line can be given by seperating them with a
semi-colon, e.g.:
send "AT\m" ; wait "OK" ; sleep 1 ; send "ATDT7582090\m" ; com
Communications mode commands: (initial settings):
F1 -- prints help file which isn't writen yet.
F2 -- invokes the "sendf" command with prompts.
F3 -- same as "cap" command.
F4 -- clear the screen
F9 -- send "\o\m"
F10 -- accepts one command from keyboard, executes it, returns to
com. Note that the command can be a script, or even, gasp,
"com", which would leave you running the communications package
under the command interpreter which is running under the
communications package which is ultimately under the command
interpreter ..... doing this sort of thing too deeply could
leave you back in DOS with a terse message "NO CORE"...
SHIFT-F1 -- Exit back to command mode
ALT-F1 -- switch 0
ALT-F2 -- switch 1
ALT-F3 -- switch 2
ALT-F4 -- switch 3
An example phone.num (which is where phone numbers reside):
cis0:7584114:300:CompuServe 300 baud only
cis1:7582090:1200,300:CompuServe 1200/300
pcbbsnyc:541-5975:1200,300:PC BBS in NYC
An example "carrier" file (att.) (two lines):
1-
,
An example "carrier" file (mci.) (two lines also):
6354192,,,,ddddd-
,
(Note that "ddddd" is the MCI access code).
An example login.csh file:
pattern reset
pattern 1 CONNECT
pattern 2 CARRIER ; : As in "NO CARRIER"
echo Dialing CIS now...
send ATDT7582090\m
wait
if match 1 connect
echo Trying alternate number...
send ATDT7584114\m
wait
if match 1 connect
echo Failure!
goto end
: connect
echo Connection made..
pattern reset
pattern 1 ":"
sleep 1
send \c
wait
send 76703,373\m ; : My ppn .. probably best to change to yours!
wait
send "this isn't my password\m"
: end
Here's a script (progra.csh) to run through The programmer's SIG and
read all new messages.
pattern reset
pattern 0 unction:
open
send "go pcs158\m"
wait
pattern 0 "RE T)"
pattern 1 unction:
send rn\m
: loop
wait
if match 1 end
send \m
goto loop
: end
close
write b:progra.tmp
Here's the script I use to visit the IBM SIG (ibmsig.csh) to come in,
catch *my* messages, do a qsn, and then set the high message counter:
pattern reset
pattern 0 unction:
open
send "go pcs131\m"
wait
pattern 0 "(C RE T)"
pattern 1 unction:
send rm\m
: loop
wait
if match 1 qsn
send \m
goto loop
: qsn
pattern reset
pattern 0 unction:
send qsn\m
wait
pattern 1 "(C RE T)"
send "rr;n\m"
wait
close
write b:ibmsig.tmp
send t\m
Here's a script that maintains and accesses a "database" of people's names
and PPNS (This is called "who.csh", and maintains the database "who.dat".
To add a ppn, give the command "who -add", otherwise, say "who <pattern>"
to receive a list of all names/ppns with <pattern> in them.):
if !same $$ 2 usage
if !fexist who.dat nodata
if same $1 -add addname
grep $1 who.dat
goto end
: usage
echo "usage: who <ppn> | <name> | -add"
goto end
: nodata
echo "no file who.dat to search"
goto end
: addname
echo -n "PPN to add:"
read 1
echo -n "Name to add:"
read 2
apl who.dat $1 "\i" $2
goto end
: end
[end]
ame
echo -n "PPN to add:"
read 1
