[opensuse] Installing additional serial ports
I have a PCI card with two serial ports. Apparently openSuSE recognizes them, but I need to mount them explicitly. I want them to be mounted at boot. Of the three ports, I want one to be for a UPS, and another for a fax modem. # dmesg | grep tty serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:08: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 0000:06:03.0: ttyS1 at I/O 0xb800 (irq = 19) is a ST16650V2 0000:06:03.0: ttyS2 at I/O 0xb400 (irq = 19) is a ST16650V2 # I wish I could say that I understand the man page on dmesg, but it is my understanding that the above is information about the presence of recognized hardware, and that the ports are not configured or operational. ttyS0 is, of course, the onboard port, and the other two are those on the PCI card. # setserial -g /dev/ttyS[01] /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16650V2, Port: 0xb800, IRQ: 19 # setserial -g /dev/ttyS[02] /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS2, UART: 16650V2, Port: 0xb400, IRQ: 19 # Again, the man page for setserial is not sufficiently clear for me to understand how to use this command.

For what it's worth : First : this is on my 10.2 system. You mentioned setserial, so you installed the package. This also installs a boot-script, see /etc/init.d/setserial. I believe this initialises your serial ports. Did you reboot ? You could also run that startup script. You say you need to mount them, I never heard of mounting serial ports. Your software should do the necessary stuff to "open" them. Maybe try minicom.

No, I didn't install any package in order to get setserial; it already exists on the system. I also find the script in /etc/init.d/

Are you saying that the script runs at boot time, and therefore the ports should be installed and configured without help from me? If so, I have to find out why the (external) modem doesn't seem to know that it is attached to anything. I begin to understand that one _doesn't_ mount the ports in fstab. I had assumed otherwise because everything else seems to work that way. Understand that I am doing me best to feel my way in this. I was surprised to find that the system had recognized the ports automatically, and asssumed that this meant only that their presence was detected; you seem to be saying that they should also be configured by now, with the script and setserial. Is that correct?

A proper modem is a dumb device, and the only "awareness" it has is the "Carrier Detect" status bit. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

It's been a while since I did this, but here goes. Is this modem for incomming or outgoing calls, it may make a differance on how to configure it. There is some info in /etc/inittab, and I think setserial is used to set port parameters, but most of it should be able to be defined on the line in inittab. Hope this helps some, Mike -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Serial ports are not mounted. Only filesystems+the devices they reside on are mounted.
I want them to be mounted at boot.
As shown below, they're already recognized by the kernel at boot time
Of the three ports, I want one to be for a UPS, and another for a fax modem.
Those are configuration issues. What do the specs for your UPS and faxmodem say?

I wish I could say that I understand the man page on dmesg,
the dmesg man page has little to do with the above information. The only thing the command line arguments do is change the "message-level", and the size of the ring buffer. The output is merely the contents of the ring buffer, which is composed of messages from all sorts of software (the kernel, and anything else which writes to the syslog)
but it is my understanding that the above is information about the presence of recognized hardware, and that the ports are not configured or operational. ttyS0 is, of course, the onboard port, and the other two are those on the PCI card.
Correct.
# setserial -g /dev/ttyS[01] /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 16650V2, Port: 0xb800, IRQ: 19 # setserial -g /dev/ttyS[02] /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS2, UART: 16650V2, Port: 0xb400, IRQ: 19 #
Again, the man page for setserial is not sufficiently clear for me to understand how to use this command. For example, man describes what should happen when the -g switch is omitted; when I run the command without the switch I am told only "Invalid flag".
SYNOPSIS setserial [ -abqvVWz ] device [ parameter1 [ arg ] ] ... setserial -g [ -abGv ] device1 ... This means that you must type the command which either conforms to the first form, or the 2nd form. With the -g flag, you can also specify -a, -b, -G, and/or -v, and MUST specify one or more devices. Without the -g flag, you can also specify -a, -b, -q, -v, -V, -W, and/or -z, followed by a mandatory specification of EXACTLY one device, optionally followed by 1 or more parameters, each of which is optionally followed by one argument, depending on the parameter, as listed in the PARAMETERS section of the man page.
What I want is to list these ports in fstab,
No, you don't. /etc/fstab is for file systems, not communications ports.
so that the ports are available upon boot.
The dmesg output above demonstrates that they're already available on boot. You just aren't configuring them properly before attempting to use them.
A few hints would be greatly appreciated.
Setserial is closer to what you're looking for. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

You dont "mount" ports, they are used as devices. If you reboot, does the kernel find the ports automagically? Search the dmesg output for any references to the serialports. this is from my ordinary workstation: dmesg|grep -i serial Serial: 8250/16550 driver $Revision: 1.90 $ 8 ports, IRQ sharing enabled dmesg|grep tty ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A Then just set the program or utility that you use for the fax/modem to use the right port. You can also test the port my using any terminal software. Just open ttys[x] with it and see what hapens. I used to play around with my old modem that way, sending hayes commands to view registers etc. Good luck! -- /Rikard ----------------------------------------------------------------------------- email : rikard.j@rikjoh.com web : http://www.rikjoh.com mob: : +46 (0)763 19 76 25 ------------------------ Public PGP fingerprint ---------------------------- < 15 28 DF 78 67 98 B2 16 1F D3 FD C5 59 D4 B6 78 46 1C EE 56 >

You dont "mount" ports, they are used as devices.
So several others have told me. I have internalized the distinction.
If you reboot, does the kernel find the ports automagically?
They do, and they did. I just didn't realize it. YaST > Hardware > Hardware Information finds the two ports on the card, and even sees the modem connected to one of them. Although I didn't know it, there has never been a problem with the ports card. I have learned a good bit from my error, and am grateful for the pointers of those who responded.
Search the dmesg output for any references to the serialports.
this is from my ordinary workstation:
dmesg|grep -i serial Serial: 8250/16550 driver $Revision: 1.90 $ 8 ports, IRQ sharing enabled
The same command here gives me dmesg|grep -i serial Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A usb usb1: new device strings: Mfr=3, Product=2, SerialNumber=1 usb usb1: SerialNumber: 0000:00:1d.0 usb usb2: new device strings: Mfr=3, Product=2, SerialNumber=1 usb usb2: SerialNumber: 0000:00:1d.1 usb usb3: new device strings: Mfr=3, Product=2, SerialNumber=1 usb usb3: SerialNumber: 0000:00:1d.2 usb usb4: new device strings: Mfr=3, Product=2, SerialNumber=1 usb usb4: SerialNumber: 0000:00:1d.7 usb usb5: new device strings: Mfr=3, Product=2, SerialNumber=1 usb usb5: SerialNumber: 0000:00:1d.3 usb 5-1: new device strings: Mfr=1, Product=2, SerialNumber=0 It shows only ttyS0 on the MB, pluse the USB ports. I don't understand the differences between your result and mine.

Then just set the program or utility that you use for the fax/modem to use the right port.
You can also test the port my using any terminal software. Just open ttys[x] with it and see what hapens. I used to play around with my old modem that way, sending hayes commands to view registers etc.
Unnecessary, since YaST tells me that the modem and the modem are present and identifiable.
Good luck!

I am pretty sure that I can access the modem device, because the modem's LEDs flashed madly when the YaST Hardware Information module was collecting information.
Probably. Then just try to use them :-)
Which is what I will do if/when I get HylaFax running.
