>How-To-Repeat:
Can only talk to the modem at 1200 bps. The modem once said that it connected at 12000 to the FreeBSD machine.  The modem works fine at 300-115200 bps on another machine with a different type of serial port. 


>Fix:
See kern/152034. It should be the same, but instead for this model of device which should be at line 421 in pucdata.c in 9.1-RELEASE.
