Re: [Freedos-devel] mode.com
Hi! MODE does indeed have verbose errorlevels in codepage handling: With FreeCOM, you can display them like this: C:\>mode con cp prepare=((437) c:\freedos\cpi\ega.cpx) MODE: No compatible FreeDOS DISPLAY driver loaded. Syntax example: ... DISPLAY CON=(VGA,437,1) C:\>echo %errorlevel% 101 Other MODE functions are more boring in their errorlevels, for example they just produce 0 if okay and 1 or 255 (-1) on error. Regards, Eric Mode is a typical example. At https://gitlab.com/FreeDOS/base/mode/-/blob/master/DOC/MODE/MODE.TXT there is a big explanation what the original mode.com from 1995 can do for me. But the last change was in 2015 - and as it looks like a lot of things were changed without a documentation, among others FD has no park function. If I understand this right, the actual errorlevels should be like this (found them at modecp.c - hopefully correct?) MODE has the following ERRORLEVEL / EXITCODES [1]: generic: 100: INTERNAL ERROR: size for prepared table too small 101: No compatible FreeDOS DISPLAY [2] driver loaded. Syntax example: ... DISPLAY [2] CON=(VGA,437,1) 102: File not found 103: Error specifying codepage / buffer 104: Error: selected buffer not present 105: Syntax error check codepage: 26: Active codepage was never set 27: Device read codepage error prepare codepage: 27: Codepage was not found in CPI file 29: Could not get codepage info from file (or XMS troubles) 31: specified CPI file is damaged (or XMS troubles) end prepare codepage: 31: INTERNAL ERROR: End prepare without Begin prepare select codepage: 26: Specified codepage was not found in file 27: KEYB failed to change codepage 29: Device select codepage failed (or XMS troubles) 31: Device select codepage error (I think 0 should be added too) The orignal looks as follows: Errorlevels returned by MODE are as follows: 0No error 115Serial port does not exist (either for COMn: or LPTn:=COMx) 117No hard disk(s) found to park 118Specified video mode is not supported on this machine 162Insufficient memory (MODE requires about 6K of memory) 241Parameter out of range (e.g. time value, LPT port number etc) 242Cannot have 43-line or 50-line modes with modes other than CO80 243Unknown baud rate 244Must specify both DELAY= and RATE= for typematic setting 246More than one command or command type was given 255Incorrect usage syntax (all usage syntax errors) Question: Which are the correct errorlevels? ___ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel

It looks to me as if you have the lists of error level from two different MODE programs. The first shows error levels regarding setting screen/video modes, while the later refers to results setting the serial/parallel port to specific values.
