I believe the mgetty communications with your modem are logged...  I
didn't reply before, as my CID modem is on a phone line without caller
ID.

On my system, mgetty is attached to a modem on ttyS3, and the log is in
/var/log/mgetty.ttyS3 .  The output looks like:

01/06 08:57:06 yS3  checking if modem is still alive
01/06 08:57:06 yS3  mdm_send: 'AT' -> OK
01/06 08:57:06 yS3  waiting...
01/06 09:15:23 yS3  wfr: waiting for ``RING''
01/06 09:15:23 yS3  send: ATA[0d]
01/06 09:15:23 yS3  waiting for ``CONNECT''
01/06 09:16:16 yS3  found action string: ``NO CARRIER''
01/06 09:16:16 ##### failed A_FAIL dev=ttyS3, pid=2869, caller='none',
conn='', name=''

01/06 09:16:16 yS3  mgetty: experimental test release 1.1.26-Apr16
01/06 09:16:16 yS3  check for lockfiles
01/06 09:16:16 yS3  locking the line
01/06 09:16:16 yS3  lowering DTR to reset Modem
01/06 09:16:17 yS3  send: \d\d\d+++\d\d\dAT[0d]
01/06 09:16:20 yS3  waiting for ``OK'' ** found **
01/06 09:16:20 yS3  send: AT&F2[0d]
01/06 09:16:20 yS3  waiting for ``OK'' ** found **

etc...

That last line of AT&F2 is the factory 2 setup command I've used to
configure the modem on reset.  You should see it change when you adjust
the mgetty config.  You see caller='none' in my case, because no caller
ID info is on that phone line.
