A newbie modem configuration question



I had problems posting to the redhat-ppp-list, so I am posting here and hoping some of you Redhat ppp gurus hang out here too :-)
 
==========================================================
 
Dear readers,
 
This is a question which probably you will have heard thousands of times
before. I hope I am posting this to the right place - all flames please to
/dev/null. Any responses by direct e-mail only please to:

I am attempting to configure my modem for use with pppd to establish a
dialup connection with an ISP (hopefully Freeserve). I hope to use software
like Netscape and Pine on my Linux partition, while continuing to use
Windows 98 clients on my dos partition.
 
The modem sits on COM4 (== cua3 under Linux) on dos, and works fine with the
connection software provided by Tiny Online.
 
I am running Linux 2.0.36 with the Red Hat distribution version 5.2,
distributed with PC Plus magazine.
 
I have been attempting to follow the instructions given on p211 on the May
1999 issue of PC Plus, with which the Linux distribution came, in order to
establish a connection to and register with Freeserve. I set the modem
configuration from the Red Hat control panel to cua3, and made some
alterations to files under /etc, following the instructions.
 
Now I have problems, because I do not know what at 'AT' command is, and I
have never used Minicom ! I tried typing the Freeserve number in the dialing
directory, and selecting 'dial'. Nothing happened. No sound, nothing. It
just timed out after 45 seconds. I tried typing in the number manually into
Minicom. Same result. I tried altering the cua number. Same result.
 
So I went and found some documentation. Very impressive, and a lot better
than since I was last administering a Linux box 5 years ago... The problem
is, that I simply cannot understand the relevent section of the PPP-Howto
document.
 
Could some kind soul please illuminate me on how to get going with this modem?
 
Information gleaned from control panel under Windows 98:
 
The modem is a V.90 K56Flex HSP PCI Modem, port COM4, Interrupt 11,
Address D800, UART Unknown chip, Highest speed 115K Baud.
 
Diagnostics:
 
Command          Response
=======          ========
 
AT1   A97/C00
AT2   OK
AT3   PCtel 7.5504MS
AT4   PCtel Data/Fax/Voice/Speakerphone/V.80
AT5   OK
AT6   OK
AT7   OK
AT+FCLA...  0,1,8
 
No modem installed on COM1 or COM2.
 
No conflicts although ACPI IRQ Holder for PCI IRQ Steering also
has interrupt 11.
 
Thanks very much,
