From: Keith Petersen <W8SDZ@Simtel20.ARPA> MXO-SY20.ASM is a MEX overlay for the Sanyo MBC-1000 Computer. THIS OVERLAY MAKES USE OF TIMER 2 OF THE 8253 PROGRAMMABLE INTERVAL TIMER (IC4) ON THE SERIAL I/O BOARD OF THE SANYO MBC-1000 AND REQUIRES A HARDWARE MODIFICATION. The overlay allows use the "SET" command to change the baudrate when desired. It starts out at 1200 baud when the program is first called up. Only 300 & 1200 Baud are enabled; info for other baudrates is provided in table form in the overlay. The SET command allows the user to change the baud rates, and the parity. The parity options are: No parity (NONE); Even parity (EVEN); Even parity with 8 data bits (EVEN8); Odd parity (ODD); and Odd parity with 8 data bits (ODD8). EVEN8 and ODD8 are for special purposes and will most likely never be used. The file is available from SIMTEL20 as: Filename Type Bytes CRC MICRO:<CPM.MEX> MXO-SY20.ASM.1 ASCII 20659 4989H --Keith
