Flow Control Flow Control regulates the internal flow of data between the 833IS software and the
modem.The 833IS has been set up to use hardware flow control and this value
should not have to be changed. However, if you enable software flow control in the
modem (via the modem initialization strings), you may need to modify these values.
No Flow Control
When set, the 833IS will ignore any flow control indication from the modem.
Hardware Flow control
When set, the 833IS will use hardware flow control with the modem.
Xon/Xoff Flow Control
Also known as software flow control. When set, the 833IS will use characters
received from the modem to flow control. The Xon/Xoff fields display industry
standard values.
Data
Forwarding In order to optimize the connection to the Dial-Out client, the 833IS will collect
individual characters received from the modem into a packet and forward this packet
to the client. The parameters in this section dictate the conditions that will cause the
packet to be forwarded.
Packet Size
Enter the maximum number of characters that the 833IS will collect before
forwarding the packet to the Dial-Out client. The default setting is 140 characters.
The minimum value is 1 character, and the maximum is 512 characters.
Setting the number lower increases the frequency of network transmissions because
the packets are always sent when they are full. This results in higher LAN traffic. If
you change the packet size, review the setting for the Packet Time Out.
Character Timeout
The maximum time that can elapse between characters received by the modem. If
this time limit is exceeded, the packet will be forwarded to the Dial-Out client. Enter
the duration of the Character Time Out in milliseconds. The default value is 60
milliseconds, with a maximum value of 65535 milliseconds. The value should be
lower than the Packet Timeout.
This number can be decreased to improve the response at the client. It can be
increased to reduce the frequency of network transmissions.
