      I'm currently working with a Sierra MC7354 card on a Netgate RCC-DFF-2220 board, alongside pfsense 2.3.2. Yesterday I had the card connecting and I was able to ping websites, ie google.com and the like. Today I tried to make some changes resulting in a loss of connectivity. After rolling back my configuration I'm still unable to connect to the card. Below is a readout of my system log:

      Jan 21 20:24:13 ppp [opt1_link0] Link: reconnection attempt 107 in 4 seconds
      Jan 21 20:24:17 ppp [opt1_link0] Link: reconnection attempt 107
      Jan 21 20:24:17 ppp [opt1_link0] uu_lock(cuaU0.2): read error: File exists
      Jan 21 20:24:17 ppp [opt1_link0] MODEM: Fail to open serial port /dev/cuaU0.2 on speed 115200
      Jan 21 20:24:17 ppp [opt1_link0] Link: DOWN event
      Jan 21 20:24:17 ppp [opt1_link0] LCP: Down event

      These same lines repeat. Any ideas why I'm unable to connect to the modem, despite having the proper speed (115200) and being on the AT serial port?
