Top of list Index page SERIAL Example: [SERIAL] COM_SENDQUEUE=2048 By default, the send queue size is 1024 byte. If it is planned to use PPP server or PPP client the size should be set to 4096. [SERIAL] COM_BAUD=BAUD Rate Comments Sets the BAUD rate of the COM port. Example: Top of list Index page SERIAL [SERIAL] COM_BAUD=9600 By default, the BAUD rate of the COM port is 19200 (with 8 data bits, no parity, 1 stop bit). [SERIAL] EXT_BAUD=BAUD Rate Comments Sets the BAUD rate of the EXT port. Example: Top of list Index page [SERIAL] EXT_BAUD=9600 By default, the BAUD rate of the EXT port is 19200 (with 8 data bits, no parity, 1 stop bit). DOSLOADER [DOSLOADER] Page 72 / 400
MEMGAP=Paragraphs Comments Sets a memory gap between the loaded DOS programs as a memory reserve. Some programs compiled with Borland C 5.02 (other compilers??) try to increase their program memory block at runtime. This can occur, for example, when opening a file with Borland C-library function fopen, where some additional memory is required. The Borland C-library fopen function calls int 21h 0x4A, which is not directly visible to the application programmer. This memory resize call fails if another program is loaded after the previous one, because now there is no memory space left for increasing the memory size of the previously executed program. The program then returns from fopen with an error. In this case, the global program variable errno is set to value 8 (not enough memory). To prevent this error, the <strong>@CHIP</strong>-<strong>RTOS</strong> allows a memory gap of a defined size between loaded programs. This memory gap size is specified as a number of paragraphs (where 1 paragraph == 16 Bytes). This strategy can fail when programs are terminated and restart again. Example: [DOSLOADER] MEMGAP=128 By default, MEMGAP is set to 0. The maximum value is 2048 paragraphs, where any value larger than this is truncated to 2048 Related Topics Set memory gap API function Developer Notes It is not necessary to set this entry if the application doesn't show the described error. Only if a C-library function call sets errno to 8, should this value be defined. We recommend in that case a value of 128 paragraphs (2048 Bytes). The described problem was noticed when the Borland C-library function fopen was used. The same can happen with usage of C-library function malloc using memory model Large. The malloc returns a NULL pointer in this case. Top of list Index page BATCH [BATCH] BATCHMODE=0/1 Sets the batch file execution mode of DOS programs. BATCHMODE=0 : (Default mode) The programs listed in the batch file will be executed concurrently, starting one after another, without waiting for completion (or going resident) of the predecessor program. The only exceptions are the WAITand REBOOTcommands. Page 73 / 400
