Abovementioned applications call BDOS functions (CALL 0005h) with networking BIOS in the CPU bank 1. For normal operation, including abort routine when CTRL-STOP is pressed on user input routine, CPU bank 1 must contain TPA RAM. Please redesign applications to turn TPA RAM on when calling any of BDOS functions, or use far calls (RST 30h) to access networking BIOS.
