[lug] looking for strings,

I can't solve a no carrier modem issue.

I read the HOWTO and then deleved into the BLUG archives.  About ten pages
of info, the one tid bit that I used was to change out a V4 to a V1
setting on the initial dial string.  

Everything is via minicom.  And I can step through checks ATI0-ATI20 with
most coming back OK and one number kicking out Parallel 16550 EXT HYB 
V32BIS V42BIS.  The AT&8 kicks out the Active register, the Stored 1 & 2
register settings.  Below that load of info are four slots for telephone
numbers.  0 emtpy 1=2305336 2= empty 3=3etmpy  and I don't know where that
number applies, I did not key it into the dialer or elsewhere.  This page
then ends with OK.

I did a google search on "NO CARRIER" +modem +linux and did not seem to
pull up anything of use save for much discussion about setserial.  

I do suspect I have an issue with the initial strings, but I did not find
any good info on how to change the initialization strings.  

The modem is date stamped AST Research 1994, which should mean that it is
not a winmodem issue.  It is 14.4K; a real pokey modem.  

Is there an O'Reilley book that might offer a few leads?  My Linux books
just have a bare one page on minicom, and I don't have the modem manual.

One last thing, I did wipe out the locked file entry thinking that might
be causing a snag, but then I put it back, /var/lockfile.  

Don't spend too much brain effort here, as the utility of a working modem,
on this 486 box, it not a critial matter to me.  It is just the exercise
of getting it right; working.
