[Xastir] Xastir is not reading APRS reports from my Kenwood TH-D7(g)

[Jake]

Problem:
Xastir is not reading APRS reports from my Kenwood TH-D7(g).

Information:
Dell Latitude CPt
Xastir v1.8.2
Kubuntu 6.10
COM1 enabled in BIOS
Kenwood on "Device 0 UP Serial TNC /dev/ttyS0".
Using Xastir defaults.
dmesg reports: serial8250 ttys0 at I/O 0x3f8 (irq=4) 16550A
Kenwood has the TNC turned on and I can see the APRS objects on the Kenwood
screen.

Any ideas of how I can make this work or troubleshoot?

Thank you,

Jake
