#4494: pppd broken if serial driver can't handle big data

Cloned from #4493:
----
The current implementation of ppp assumes (in ppp_tty.c:pppstart) that
sending characters via the termios device write function will send buffers
of any length. That is not true for most drivers.
Devices that can only send one character at a time won't work with that at
all. Devices that have a big enough FIFO might work most of the time.
Devices that use a DMA for transmitting might work without problems.
