USR Internal modem question

I'm trying to get a USR internal modem, working and am getting something
I've never seen before. I've done quite a few modems in the past, but
they've all been external, and I've never seen anything quite like this.
I've got both an internal and external sportster on the same system,
although I'd like to just use the internal, since it's a 1U rackmount
system with a single serial port that I'd like to use as a console port.
When I call into the external modem everything works fine. When I call
into the internal modem the Password prompt stays on the same line as the
userid that was typed in. After logging in everything seems to work fine
except there are no prompts from the shell. If I use watch from another
session telneted in it looks like the system is putting the return after
entering the userid and the prompts in the buffers, but they're not getting
sent out the modem.
The system is an IBM x305 with a single build in serial port, running
FreeBSD 5.0-RELEASE-p7. The serial is sio0 and the PCI modem is sio4.
There aren't any settings on the internal modem card itself, dips or
jumpers, so I seem to be stuck with what PnP gives me.
The external modem (ati3) id's itself as "U.S. Robotics 33600 Fax V5.8.3"
and the internal modem id's as "U.S. Robotics 56K FAX INT V5.22.45". The
internal is the performance pro, not a winmodem. The modem settings are
identical; The only difference I can see is one is internal and the other
is external, The startup messages about the serial ports are
sio0: <3COM PCI FaxModem> port 0x5000-0x5007 irq 3 at device 2.0 on pci1
sio0: moving to sio4
sio4: type 16550A
sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
sio0: type 16550A
sio1: configured irq 3 not in bitmap of probed irqs 0
sio1: port may not be enabled
These are the various modem and config files.
