I got an interesting clue by trying ECU. Check this out: ECU is a dialer type program. I told it to use /dev/ucom0 to dial my desk phone number, and it showed itself trying to issue a bunch of commands to the modem, but each time they came back and said missed expected carriage return. It eventually gave up, but my phone then started ringing! Dialing telno 23645 on /dev/ucom0 at 9600 baud (10:24:25) Trying ecu dialer /usr/local/lib/ecu/ucom0.mi: No such file or directory modem init string not found (using default 'ATE1Q0V1') modem dial string not found (using default 'ATDT') ATE1Q0V1 missed expected carriage return got nothing ATE1Q0V1 missed expected carriage return got nothing ATE1Q0V1 missed expected carriage return got nothing ATE1Q0V1 missed expected carriage return got nothing /usr/local/lib/ecu/ucom0.mi: No such file or directory modem init string not found (using default 'ATE1Q0V1') modem dial string not found (using default 'ATDT') ATE1Q0V1 missed expected carriage return got nothing ATE1Q0V1 missed expected carriage return got nothing ATE1Q0V1 missed expected carriage return got nothing ATE1Q0V1 missed expected carriage return got nothing ATDT23645 missed expected carriage return Cannot talk to modem When it was over, I did a tip on the same device and it spewed a bunch of garbage at me: OK AT OK ATQ0V1E1 OK ATE1Q0V1 OK AT OK ATQ0V1E1 OK ATE1Q0V1 OK AT OK ATQ0V1E1 OK ATE1Q0V1 OK ATE1Q0V1 OK AT OK ATQ0V1E1 OK ATE1Q0V1 OK AT OK ATQ0V1E1 OK ATE1Q0V1 OK AT OK ATQ0V1E1 OK ATE1Q0 So all the commands were going through, but somehow being buffered...? Any knobs I can play with to help with this situation?

Core dump with tip (ucom0 - external modem)
Hey everybody, I am trying to set up a FBSD 5.2.1-RELEASE machine to be able to dial a number via tip as described here: http://docs.freebsd.org/doc/5.1-RELEASE/usr/share/doc/faq/serial.html (That page is a bit out of date, at least in that it says it applies to FBSD 2, 3, and 4.) My HW setup is an old pentium box with a USB to Serial cable attaching to a USR external 56k Modem. I added this to my /etc/remote tip115200|Dial any phone number at 115200 bps:\ :dv=/dev/ucom0:br#115200:at=hayes:pa=none:du: tip57600|Dial any phone number at 57600 bps:\ :dv=/dev/ucom0:br#57600:at=hayes:pa=none:du: cu115200|Use cu to dial any number at 115200bps:\ :dv=/dev/ucom0:br#57600:at=hayes:pa=none:du: tip9600|Dial any phone number at 9600 bps:\ :dv=/dev/ucom0:br#9600:at=hayes:pa=none:du: But the suggested command gives me core: tip -115200 23645 Segmentation fault (core dumped) Same result with -57600, -9600 and with cu syntax I have an entry for the usb serial device: usb1:dv=/dev/ucom0:br#9600:pa=none: And if I say tip usb1 I can issue dialer commands and it works. The ultimate goal here is having somebody be able to run a shell-script named dial-funkybox and have it dial and connect them. Sorry if I left out something important. Any thoughts?
