Presuming that this is the log from your system, the log says that you are
sending a config request but not receiving a response from the ISP.

Not important, but you might want to use ttyS0. The cua devices are
deprecated. I wish RedHat would remove them.

This is an odd value, but I don't see any documentation saying it
shouldn't work. The minimum is 128, the recommendation for slow links is
296 (256 bytes + 40 bytes overhead), and I usually expect (256*n)+40
(e.g., 552 for n=2). You might want to comment this out (i.e., use the
default 1500) and see what happens.

You send the request, yet receive no response. If you use chat, add the
-v (verbose) option and examine the output. Although you tested the
connection with minicom, you might have missed something. It appears that
the remote side isn't running pppd, yet.
