I'm looking to utilize one of the TTL uarts provided by the FPGA on the TS7800.   Thus far, I've been unsuccessful in configuring the ports.  The module is loaded and dmesg reports they have been identified as you can see...

Jan  1 00:00:46 ts7800 kernel: ttts0 at MMIO 0xe80000c0 (irq = 80) is a TSUART          
Jan  1 00:00:46 ts7800 kernel: tt8s0 at MMIO 0xe80000c0 (irq = 80) is a TSUART          
Jan  1 00:00:46 ts7800 kernel: ttts1 at MMIO 0xe80000c4 (irq = 81) is a TSUART          
 

Following that I've tried several variations of setserial options to get the serial port properly configured for operations.   Thus far, everything has failed.   Anyone have any luck getting them setup via setserial so I can autoconfigure them on bootup?   I've also tried just using minicom / ckermit via a loopback cable and that fails as well since the device isn't properly configured.  

The archives seem to point to just raw configuration via C code.  Doable but it would be nice to have them properly configured so I can use minicom to configure and evaluate communication with the attached device.   

Suggestions?
