AW: [Hbasic-userinfo] Serial Port

[Engels, M. <Mar...@SP...>]

Hello Tullio,
=20
I don't know very much about serial ports. I tried to find some info in =
the
"Serial HOWTO" but it didn't help me very much to find the API =
functions
that will be required to read or write to the serial port with linux.
Currently I want to implement support for all classes of the Qt library =
but
I couldn't find some classes that may be used for serial IO in this =
library.
Maybe it's usefull to call shell functions like settty with the =
system()
method in HBasic but I'm not sure about that.

I'm not sure how you mean with using API calls in VB (maybe because I =
don't
know every feature of VB). To call functions of another library that =
has
been created with C or C++ code HBasic needs some additional C++
wrapper-code to understand how HBasic function calls to the API methods
should be converted to C++ methods. I call this wrapper code a package. =
A
package may be loaded dynamically at runtime of HBasic and add's the
implemented API interface to HBasic. The normal widgets like Button or =
Label
for example are functions that connect to the appropriate Qt API =
functions.
This means if you want to use new API functions you will have to create =
some
wrapper code in C++ first. You may take a look at the HBasic docu at

Betreff: [Hbasic-userinfo] Serial Port


I'm new to HBasic because i discovered it reading a mail from =
Lindows.com.
=20
Currently I'm developing in VB and Windows but I would really like to =
start=20
=20
my migration to Linux and HBasic.
=20
 I have few question to the list:
=20
How is supported in HBasic the serial port?
=20
In my code I'm often using API calls. Is there something similar in =
HBasic
and Linux?
Where I can find more about?
=20
Tanking in advance

Best regards
