Except it recommends switch 5 be on/down too. It doesn't bother to describe the switches, but my other manual says it's for "auto answer" so it's position shouldn't matter for this problem. Of course, my internal modem has no switches at all, so it can't help with the internal modem problem. FreeBSD surely should support hardware flow control (it's in "stty"), but I guess I can try an XON/XOFF configuration; I don't have a distinct memory of trying that on the external modem. > Modem has to be powered on before you boot FBSD box modem is cabled > to. Now, THAT could be my problem in the case of the external modem. I thought the drivers were smarter than that; rebooting is nasty, when serial lines are hot-pluggable.

I've no mswindows to run, but I've tried three different serial ports on the motherboard and ISA card. I've probably tried the other things you suggested; I hoped there would be some hints about software configuration that I had missed. But I can do more experiments with other modems and other computers and Linux to determine whether the problem is in the hardware or software.

RE: Modem replies to commands mostly not seen.
I have a USR sportster 14.4 external serial modem which works fine
under FBSD 4.8.
Dip switches 3-7-8 are set to 'on' which is down, all others are set
to off which is up.
3 = display result codes
7 = load factory defaults
8 = smart mode
Modem has to be powered on before you boot FBSD box modem is cabled
to. Modem is found and listed in /var/run/dmesg.boot file. During
PC post process a summary PC hardware config screen shows the irq's
assigned to hardware. Check this summary screen to verify the irq
assigned to modem is not shared with other hardware. If it is, go
into pc bios to change, be sure bios plug-n-play option is disabled,
and serial ports are enabled. I use "TIP" command to issue Hayes AT
commands. If you get an OK response to AT command, then you are
talking to modem just fine and it's working. If you still have
problems, post dmesg.boot file and use the script command to log
your TIP command test output to a file and post that also. Most PC's
have 2 serial ports, try cabling modem to different port and test
again. Can you run mswindows on the pc to verify serial port and
modem work.

I tried the external Sportster under 4.8 but after it wouldn't work,
I upgraded to 5.1 to lower the chances of having to go through this
again when I did switch.
I have modem manuals and played with dip switches and lots of AT
commands including "ATE1" ("keyboard commmands"), "ATF0" (I think
that's only for data that the modem sends out the phone line),
"ATX4"
("result codes"), re-init commands ATZ, ATZ1-ATZ5, AT&F1, and many
others. I've been through this several times before (on Linux) and
think I know what I'm doing (except I've never understood the
interactions of "stty" and serial-port-using programs like terminal
emulators. It's strange that "ATI" gives it's results if I press
keys, but "AT" or "$" don't.
I've found a place to do my FAXing, so the pressure's off on getting
this fixed.
BTW, my other question was about the dmesg files, but I should have
thought of the HISTORY_SIZE thing for at least the console.
(/var/run/dmesg.boot has 943 lines of nothing I care about.)
Someone suggested "kern.consmsgbuf_size=16384".
Thanks.

RE: Modem replies to commands mostly not seen.
Sounds like you have echo turned off in the modems internal prom setting. Use Hayes AT command to turn on echo function of modem hardware. Did these modems you tested work ok in FBSD 4.8? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Gary W. Swearingen Sent: Monday, July 14, 2003 12:26 AM To: [EMAIL PROTECTED] Subject: Modem replies to commands mostly not seen. I hooked up an external 28.8 modem after continuity-cheking the cable but the lights didn't seem right, as I remember them. (I've not use my modem for several years.) Modem doesn't respond to terminal emulator commands and seems broken, so I throw in an internal (non-winmodem) Sportster (that I've just seen working OK under Linux). Boot message looks OK as it flashes by; it identifies the proper UART, IRQs, etc, (but not an ID string from the modem -- I don't know if that's expected or not). I hand-set the "COM #" and "IRQ" and made things match in /boot/device.hints. And it sort of works. I'm using "/dev/cuaa3". When I run a terminal emulator (tip, seyon, and minicom, so far), I get the same behavior: 1) Each character typed isn't seen until I type the next character. 2) Giving it the "AT" command (or most others), it never says "OK", but a few info commands, like "ATI6" will slowly spit out their reply (even ending with "OK") if I bang away on the keys, one or two characters per key. Looks like some kind of flow-control problem, but I've tried lots of fixes (using the terminal emulator's config controls) and always get the same behavior. I've even messed with some of the "stty" stuff, though I think that should be overruled by the terminal emulators (except maybe "tip", which I barely know). Any hints?
