Hi John,

I encountered some problems while trying to install ExtendedSerialPort
on Linux... - latest vm 3.7-7

Compile error:

/src/plugins/SerialExtendedUnixPlugin/SerialExtendedUnixPlugin.c: In function `primitiveSerialPortUnixCfgetispeed':
/src/plugins/SerialExtendedUnixPlugin/SerialExtendedUnixPlugin.c:127: warning: passing arg 1 of `cfgetispeed' from incompatible pointer type

Moreover there is a problem about undefined function : int
serialPortFindNamesPlusKeysstorage(int aUpperNumber, char
*aByteArray);

Two primitives used this function, I deleted it to see what will
happen. I added quickly a SerialPortTermiosUnix and then this
primitive failed :

primitiveSerialPortUnixTcgetattr: afd attributes: aByteString 
<primitive: 'primitiveSerialPortUnixTcgetattr' module:'SerialExtendedUnixPlugin'> 

So I think maybe the problem is with tcgetattr(fd,atermios) : I saw in
the appropriate .h that this function eats a structure, and we give it
a char* (atermios) ? Tried to compare with MacOS version (in
squeak.hpl.hp.com) but there is sometimes no plain code
(SerialExtendedPlugin.pbproj.sit and don't know what is this beast).

Since I'm not a C-pecialist, I'm stuck ! :-)
