Hardware (RTS) flow control of the ACIA is provided. The ACIA transmit interface is also buffered, with direct cut-through when the 31 byte software buffer is empty, to ensure that the CPU is not held in wait state during serial transmission. @@ -30,7 +30,7 @@ The IDE Hard Drive Module supports both PATA hard drives (including 3 1/2" magne The CP/M-IDE system supports up to 4 active CP/M "drives" (files) of nominally 8 MBytes each.

Collections of hundreds of CP/M drives can be stored in any number of sub-directories on the FAT32 disk.
