Computer Interface H4: Parity Parameter value 0 1 2 3 Baud rate None Odd Even Ignored The factory setting is 0 (none). H5: Protocol logic Parameter value 0 1 2 3 4 Baud rate Combination of DTR (positive logic) and XON/ XOFF DTR (positive logic) DTR (negative logic) XON/XOFF ETX/ACK The factory setting is 0. H6: Buffer nearly-full threshold A percentage value from 0 to 99. The factory setting is 90. H7: Buffer nearly-empty threshold A percentage value from 0 to 99. The factory setting is 70. The factory settings of the buffer nearly-full and nearly-empty thresholds (H6 and H7) are subject to change without notice. The difference between the nearly-full and nearly-empty thresholds allows the computer to send a fairly large amount of data in a continuous stream. H8: Received data buffer size The input buffer size is specified in increments which vary depending on the S5 parameter. When S5 is 0, the increment is 10KB. When S5 is 1, the increment is 100KB. When S5 is 2, the increment is 1024KB. The factory setting is 12 (1200KB, S5=1). 4-8 ADVANCED OPERATION GUIDE
