You're continually seeing corrupted messages from the USR modem.  Thus, 
" CARRIER" is not a system log hiccup.

In theory, yes, it could cause a problem, but it's not likely to have 
been a factor at all for any reason with only two modems and a system 
that's no more than 10 years old.

In any case, logging of modem I/O does not cause the modem to screw up 
I/O.

Replace the USR modem.  If the problems persist then there may be a 
problem with the serial port.

Observe the problem in the log you just sent:

"NO CER" is not a valid response.  The modem is screwing up the 
response somehow.

You don't happen to be running some other program against that modem 
also, do you (i.e. running minicom and faxgetty at the same time)?
