6.1.3 Baud Rate Selection
The communications baud rate for COM1 is selected by using the menu under OTHER BAUD-RATE.
See Section 5.1 for details on using the menu. The factory default setting is 9600 baud.
After selecting the baud rate, this value is retained in non-volatile memory and need not be re-selected as
long as the same baud rate is desired.
The baud rate for COM2 is selected by the C2B# command. (See Section 6.2.16) This value is retained in
non-volatile memory and need not be re-selected, as long as the same baud rate is desired.
6.1.4 XON/XOFF Handshaking
The RS-232C output has XON/XOFF capability to prevent data loss when used with computers and
devices with XON/XOFF capability. Handshake control must be set to HARDWARE if 38.4 baud is
selected.
The standard CONTROL-S (ASCII 19) and CONTROL-Q (ASCII 17) characters are used to pause and
resume data output from the MTS-1710. These may be used manually, if desired, to pause the display.
