Serial Port Configuration
The DS-Series host modules can use different serial port configurations as shown in Figure 16.
Handshaking, Baud Rate, Word Size, Stop Bits, and Parity can all be configured through the serial port
using the menus. RTS Line Driver, and DTR Line Driver cannot be configured using the serial port; they
must be configured using the phone line. The default settings are 9600bps, 8 data bits, no parity, one
stop bit, RTS and DTR low.

shown in Figure 17.

Attention Character
Attention Character = semi-colon (;). Pressing the attention character 5 consecutive times will return back
to the main menu. This menu allows you to change the value of the attention character for the DS series, so
as not to negate the access menu as shown in Figure 18.

Disconnect Timeguard
This feature provides reliable binary data transmission by providing a one-second “timeguard” after the
DS-Series receives the attention character. If more data is received within the delay period, the DS series
treats the character as data, not an attention character; thereby preventing unwanted port disconnection.
The Timeguard session will disconnect your session if you have been idle too long. The default setting is
disabled as shown in Figure 19.
