Establish communications with CHA: @A<# raw bytes><delim>
Establish communications with CHB: @B<# raw bytes><delim>
where <# raw bytes> is the number of bytes to follow that will be received
from the host computer which will not be scanned for changes in the serial
communications target.
Example
@ *
PP * Current pan position is 0
@A *
This text is sent directly to the serial device on CHA
@B *
This text is sent directly to the serial device on CHB
@A20 *
This @B text is sent to CHA without choosing CHB
@ *
PP * Current pan position is 0

6.1.2 Configuring Expanded Serial Port Communications
Description
Command specifies the communications parameters for an expanded serial
port RS232C communications. These commands only affect the serial data
rates for the expansion port connected to the external serial device; the PTU
controller serial port default communicates at 9600 baud, 8 databits, no
parity, and no handshaking. See section 4.7 for modifying host port
communications speed.
Syntax
@A(<baud>,<databits>,<parity>,<handshaking>)<delim>
@B(<baud>,<databits>,<parity>,<handshaking>)<delim>
where A and B indicate RS232C expansion port CHA and CHB, and:
<baud> may be 300, 1200, 2400, 4800, 9600 or 19200 bits
per second
<databits> may be 7 or 8 databits per byte
<parity> is case insensitive and may be N (none), E (even), or O (odd)
<handshaking> is case insensitive and may be N (none), H (hardware
handshaking), X (XON/XOFF software handshaking), or F (both
hardware/software handshaking)
Example
The following command sets the expansion serial port channel CHA to a
baud rate of 9,600 bits/second, 8 data bits per byte, no parity, and no
handshaking:
@A(9600,8,N,n) *
The following command sets the expansion serial port channel CHB to a
baud rate of 19,200 bits/second, 8 data bits per byte, no parity, and hardware
handshaking:
@B(19200,8,n,H) *
