[fpc-pascal] New to freepascal and how to translate my delphi program.
I am new to free pascal, but have some experience with delphi. I wrote a program to control a milling machine (Elektor Profiler, see elektor.nl/ forum program Doit). The program is written in delphi-7 ( about 25.000 lines in 20 modules) and runs on MS-Xp. But as MS changes to much in its os's I want to change to linux as os. The program uses 2 I/O-ports (serial or usb-serial) and here I have a problem in translating my program into free-pascal. I think the forms and screen layouts present no problem, it will take a lot of re-typing but oke. The serial-port problem is my main worry as the programflow depends heavely on the communication with the milling machine. My question is: where do I find lib's with serial-port or usb-port routines which I may use to control the communication-lines (bits) to the milling machine. Thanks in advance, Piet van der Wal (PE0PWA).___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] How to detect serial/usb-serial ports.
Hello, In my program I need to present the user with a list of available serial and usb-serial ports on the system they are using. How do I detect in my program these ports?. (something like GetPortList() in Delphi-7???). One port is used by a milling-machine to receive its position and speed commands, the other port is used by a controller for switching the machine automaticaly on/off and start or end of the milling and measure and detect the roughness of the surface area of the material to be processed.

For which operating system? I'd expect (recent versions of) those to only create devices that were known to exist. I detect what's available by looking for up to 12 /dev/ttyS*, 8 /dev/ttyUSB* and 4 /dev/ttyI*, then later checking that they can actually be opened (bearing in mind that this might glitch a control line). It's worth noting that a few weeks ago I was updating the standard serial.pp unit and noticed that Solaris designated serial ports as /dev/ttya and /dev/ttyb. Windows of course is \COM1, or strictly \\.\COM1 etc.; I note Fabio's test but in the past have used the registry to find e.g. named ports simulated by an AVR box. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal I'll use Mark's method of com-port detection in my program under linux and GetComPorts under Windows. In a few days time I'll let you know the result.

[fpc-pascal] How to use serial or usb-ports in linux
Hello all, I wrote a program to control a hobby milling machine.(Profiler, see Elektor-forum). The programm is written in fpc-pascal and using synaser in the windows version for control of the serial port(s). Now I want to use the program in Debian 8... and or Ubuntu 15... Compiling and running the present version gives "no permission" for the serial/usb ports. Please advise how to get the program running with these ports. (lazarus 1.2.4 fpc 2.6.4).

[fpc-pascal] How to use serial or usb-ports in linux... solved
Sven, Christo, Henry and Mark, thanks for the advice. It shows me the way to go. But due to a hardware problem it takes some time to solve and test the program again.
