INT 1A - Disk Spool II v4.0x - GET SPOOL(Simultaneous Peripheral Operation OnLine) The process of performing output to a slow peripheral such as a printer while other tasks continue running on the CPU. This term dates back to mainframe days before the invention of timesharing. FILES AH = E2h AL = which 01h first 02h next (can only call after "first") CL = printer port (01h COM1, 02h COM2, 05h LPT1, 06h LPT2) Return: AH = status 00h successful ES:BX -> ASCIZA NUL-terminated ASCII string. The ASCIZ string "ABC" consists of the four bytes 41h, 42h, 43h, and 00h. Unless otherwise specified, maximum lengths given in the interrupt list do not include the terminating NUL. filename F0h no (more) spool files FFh failed Note: this function is also supported by Vertisoft's Emulaser utility ELSPL, as that is a licensed version of Disk Spool II SeeAlso: AH=E0h,AH=E1h
