setsccbatch

Syntax

channel baud options setsccbatch

Definition This operator sets the communication parameters as specified by three integers:

channel, which designates the serial channel. Channel 9 only is available

baud rate, which determines the rate of data transfer

options, which encodes parity, flow control, the number of data bits, and the number of stop bits to be used in serial communication mode

The new baud rate and options do not take effect until the end of the current job. You may not set the serial channel’s baud rate to 0. A 0 setting will cause a rangecheck error to occur.

Example: 9 19200 2 setsccbatch sets the 8-pin serial channel to 19200 baud with even parity.

Refer to the section “SCC Operator Encoding,” in Chapter 3, for detailed information on this subject.
