Devices that don't implement param() (which means they don't support hardware parameters such as flow control, baud rate) hardcode the baud rate to TTYDEF_SPEED. This means the buffer size cannot be configured, which is a little inconvenient when using canonical mode with big lines of input, etc. Make it adjustable, but do clamp it between B50 and B115200 to prevent awkward buffer sizes. Remove the baud rate assignment from /etc/gettytab. Trust the kernel to fill in a proper value. Reported by: Mikolaj Golub <to my trociny gmail com> MFC after: 1 month
