[ts-7000] setting com1 baud rate

["mwg0627" <>]

I have the TS-7250 model and I am trying to communicate through the
serial port. My serial device requires the baud rate to be set to
19200. I have disabled getty in inittab so nothing else is using the
serial port. I have had no success setting /dev/ttyAM0 to this rate.

This is what I've done.

After reboot:

# setserial /dev/ttyAM0 -G
/dev/ttyAM0 uart undefined port 0x0000 irq 52 baud_base 921600 spd_normal

The 'setserial' man page says that baud_base is CLK / 16. Which clock?
It may be that I don't really understand how to set this parameter.
Anyhow, since the default baud rate is 115200 I figure baud_base is
being divided by 8 (921600 / 8 = 115200). So I try, 8 * 19200 =
153600,

# setserial /dev/ttyAM0 baud_base 153600

Doesn't work.

Next, I try,

# setserial /dev/ttyAM0 baud_base 19200

Doesn't work.

So, the simple question is how can I set the baud rate of COM1 to
19200? Or is there some other reason why I can't communicate on COM1?


Thanks,
Mike
