[PilotMgr] Patches to pi-port

[Andreas Jakobs <andreas.jakobs@xxxxxxxxxxxxx>]

Hi,

here are the promised patches to pi-port.c to make it work for me under
solaris.

The first part ist to accept baud rate changes and came from Rik Harris
on pilot-unix in April 98. 
The change of the timeout value for serial_read() from 1 to 500 MICROseconds
was neccessary un my Ultra under Solaris. Linux could live without.

If you start "pi-port /dev/ttya " on your machine, it waits on port 4386
for connections. These are established by using ":<ip-addr>" as a port
specification for pilot-link or PilotManager.

Be sure to kill pi-port after syncing, because it eats up CPU time by
polling the serial line :-(

Regards

Andreas
