[ts-7000] serial port question

["Wouter van Wyk" <>]

Hi

 

I have a TS-7250 with the TS-SER1 and TS-ISO485 boards installed.

The TS-SER1 has one serial port and TS-ISO485 has 2 RS485 ports (seen as 2 serial ports by linux).

 

TS-SER is configured through jumpers as COM3 (irq=7)      

TS-ISO485 is configured through jumpers as COM4 and COM5 (sharing irq 6)

 

If the board boots up COM3 COM4 COM5 is displayed in the boot-up screen. The serial driver however only reports ttyS02 and ttyS03 at boot-up. In /dev/tts the nodes 2 and 3 are created. I can write to COM3 and COM4 and everything seems to be working fine (after I did a setserial to configure the correct interrupts).

 

My question: Why is /dev/tts/4 not created? Is there a configuration parameter that limits the number of off-board serial ports that will be created?

 

Any pointers will be appreciated.

 

Thanks

Wouter
