|
|
|
<P>Since each modem has an associated serial port and the port has both
|
|
hardware and software, there are three parts to configuring a modem:</P>
|
|
<P>
|
|
<UL>
|
|
<LI>Locate the serial port hardware: IO address, IRQ; Done by PnP
|
|
methods or jumpers, setserial. See
|
|
<A HREF="Modem-HOWTO-6.html#locate_port">Locating the Serial Port: IO address IRQs</A>
|
|
<A HREF="Modem-HOWTO-10.html#set_serial">What is Setserial</A></LI>
|
|
<LI> Configure the serial port driver (high-level): Done by the
|
|
communication program (stty-like). Sets speed, flow control, etc.
|
|
See
|
|
<A HREF="Modem-HOWTO-7.html#config_stty">Configuring the Serial Driver (high-level)</A> See
|
|
<A HREF="Modem-HOWTO-7.html#stty_">What is stty ?</A></LI>
|
|
<LI> Configure the modem itself: Done by the communication program
|
|
See
|
|
<A HREF="Modem-HOWTO-8.html#modem_conf">Modem Configuration</A></LI>
|
|
</UL>
|
|
</P>
|
|
<P>The above omits a few other things that "setserial" can do besides
|
|
locating the serial ports. But normally you don't need to use them.
|
|
Setserial may be used in the future to enable super-high speed.</P>
|
|
<P>Communication programs include <CODE>minicom</CODE>, <CODE>seyon</CODE>, or
|
|
<CODE>wvdial</CODE> (for PPP) and <CODE>mgetty</CODE> for dial-in. Such
|
|
communication programs require that you configure them, although the
|
|
default configuration they come with may only need a little tweaking.</P>
|
|
<P>Unfortunately the communication program doesn't locate the serial
|
|
port. This "locating" is the low-level PnP configuring of the serial
|
|
port: setting its IO address and IRQ in both the hardware and the
|
|
driver. If you are lucky, this will happen automatically when you
|
|
boot Linux. Setting these in the hardware was formerly done by
|
|
jumpers and then running "setserial" but today it's done by
|
|
"Plug-and-Play" software. You may still need "setserial". So if
|
|
Linux (or the wvdial program, etc.) doesn't report what serial port
|
|
your modem is on, then you can try to find it yourself per the next
|
|
section but it may not be easy.</P>
