calling kermit script through JSP page
hi all,
I would like to thank all of you and greatly to the "creator" of
kermit, Mr. Frank.
I was able to get connected to a GSM modem and was able to transfer a
100kb of file from one end to other using kermit.
The kermit script(following) is written to attain the functionality.
The script when executed from the terminal executes well,
like this "./script_name "
But i am facing a small problem...
when the script is called from a JSP page it partially runs!
meaning ...please see the following comments in brackets in script.
#!/usr/bin/kermit + ;SCRIPT START
set disconnect on
set line /dev/ttyS0 .....(DOES NOT WORKS)
open write /vikrant/check.txt......(WORKS)
write file \%1 \%2 ......(WORKS)
close write-file ......(WORKS)
set exit warning off
cd /vikrant/inbox
set dial timeout 70
dial \%1 .....(DOES NOT WORKS)
if fail exit 1
kermit -g /vikrant/outbox/*\%2
exit ;SCRIPPT END
Meaning ...the 3 line are executed which writes 2 parameters
into a file "check.txt"
the "set line" and "dial" command is not executed ...where as, it is
all executed
when invoked from terminal
what probably would be the reason ?
with regards
Vikrant

Re: calling kermit script through JSP page
Well i got the solution for the above problem
the solution was :
"set line /dev/ttyS0" ...was not working because the jsp page was not
having permissions to LOCK the /ttyS0 (i.e. comm1)port.
i.e. the file /var/lock was not having sufficient permissions.

This is documented in the manual, and also here:
http://www.columbia.edu/kermit/ckuins.html#x10
(Sections 10 and 11).
Also, as noted in the script-writing tutorial:
http://www.columbia.edu/kermit/ckscripts.html
any command that can fail should be followed by an IF FAIL command that
catches the failure, so that the script does not continue executing as
if the failed command had succeeded.
