I was referring to minicom command similar to one on linux. 
On linux the config file is /etc/minirc.<configfile> and the  Serial Device is  /dev/ttyUSB0, which was working for me.
On freebsd  the config file is /usr/local/etc/minicom/minirc.<configfile>, but not sure what to update in the field 'pu port'. 

I tried with /dev/ugen2.2 but got below error
> minicom: cannot open /dev/ugen2.2: Permission denied

Please let me know what needs to be updated in the 'pu port' field.

I take it a minicom is a external serial modem for internet access over the phone lines.

First off you better check if this is a windows modem.

Phone modems are manufactured for two target markets, MS/Windows (Winmodems) and every thing else. Winmodems are cheep because the hardware controller function is handled by the software you have to install into MS/Windows. This hardware controller function is normally contained in a chip on the modem circuit board. Winmodems are missing this chip and directs the modem to use driver software running in the MS/Windows system to perform the controller function. The most common Winmodem chips are manufactured by Lucent. There are many versions of this Lucent chip resulting in each chip version needing a different MS/Windows software driver version.

Up until version 4.4, FBSD did not have any solution to using Winmodems, but with the release of 4.4 the ports collection now contains the "Linux Winmodem 'ltmdm' driver" which was ported to FBSD. This port is very poorly documented, only works with a limited number of Lucent chip version, and can be somewhat unreliable. Your whole Internet connection is managed by your modem and trying to shoe horn a modem specially manufactured for the MS/Windows operating system into FreeBSD is not the way to achieve a satisfactory dialup Internet connection.

Plug the usb to serial converter into a usb port on the pc.
Plug the serial cable into the modem and the converter.
Power on the minicon, and boot your pc.
Check your boot messages for the address of the usb to serial converter
and use that address in your ppp config for dialing your ISP.

If you can't id the address you need, then post your boot message log here for next step in help. Use dmesg > boot.msg.file to get a copy of the boot log.
