I am trying to figure out how to set the baud rate on a USB SERIAL
device to 34800 or higher.

In the past with regular tty devices I would use setserial and
use spd_hi or spd_vhi or spd_shi .. etc.. and then
set the port baud rate to 38400 and you would get the higher speeds
like 57.6 K or 115k or 230K etc..

But setserial does not recognize my USB serial device as being a
"serial" device.

Is there another way to do this?


I was able to get my LG cell phone to work as a modem but currently I
am limited to a USB-serial speed of only 19200. The phone supports
115200 and 230400.

I forgot to add.. this device uses the pl2303 usb-serial driver.
