* contrib/hbtcpio/tcpio.c
* use default timeout defined in initial hostname string in read/write
operations
* include/hbapicom.h
* src/rtl/hbcom.c
+ added new C function:
int hb_comFindPort( const char * pszDevName, HB_BOOL fCreate );
It check if given port name is already defined and if not and second
parameter fCreate is TRUE then it allocates such port in one of last
free slots. On success port number is returned. If port cannot be
found or created 0 is returned.
* include/harbour.hbx
* src/rtl/hbcomhb.c
+ added new PRG function:
hb_comFindPort( <cDeviceName> [, <lCreate> = .F. ] ) -> <nPort>
* contrib/hbplist.txt
+ contrib/hbcomio/comio.c
+ contrib/hbcomio/hbcomio.hbc
+ contrib/hbcomio/hbcomio.hbp
+ added new Harbour FILE IO redirector.
It recognizes and process names with "COM<n>:" prefix, in form like:
COM<n>:[<com_params>]
<n> is port number or port name prefixed with "$" character.
<com_params> may contain serial port parameters like baud rate, stop
and data bits, parity and flow control (XON,XOFF,CTS, RTS,DST,DTR).
As delimiter comma "," is accepted.
This redirector can be used in different subsystems using Harbour
FILE IO and stream read/write operations, i.e.
REQUEST HB_COMIO
SET PRINTER TO COM2:38400,N81,XONXOFF
can be used to connect to serial printers.
Please remember that redirectors like NETIO can be used as wrapper
to other redirectors so code like:
pFile := hb_vfOpen( "NET:192.168.0.1:::COM1:9600,8N1" )
opens 1-st serial port on the server and
pFile := hb_vfOpen( "NET:192.168.0.1:::COM$/dev/ttyUSB0:9600,8N1" )
opens "/dev/ttyUSB0" serial device on the server.
