Description
usb_serial seems to occasionally insert control characters and also seems to lose data.
To see the problem we have two machines linked with a serial cable, running at 57600 baud.
On the Haiku system we am sending simple ascii files, repeatedly, such as:
11111111111111111111111111111111111111 22222222222222222222222222222222222222 33333333333333333333333333333333333333 44444444444444444444444444444444444444 55555555555555555555555555555555555555 66666666666666666666666666666666666666 77777777777777777777777777777777777777 88888888888888888888888888888888888888 99999999999999999999999999999999999999 00000000000000000000000000000000000000
The output on the other machine shows things like:
11111111111111111111111111111111111111 22222222222222222222222222222222222222 33333333333333333333333333333333333333 44444444444444444444444444444444444444 55555555555555555555555555555555555555 66666666666666666666666666666666666666 77777777777777777777774444444444444444444444444444444444 55555555555555555555555555555555555555 66666666666666666666666666666666666666 77777777777777777777777777777777777777 88888888888888888888888888888888888888 99999999999999999999999999999999999999 00000000000000000000000000777777777777777777777777777777 88888888888888888888888888888888888888 99999999999999999999999999999999999999 00000000000000000000000000000000000000

I the log files we see lines such as:

On OHCI we may not have seen the corruption, though the loss of data still occurs:
