TCP Settings
Description
The TCP settings are configured using two menu items. The configurable values are:
zTCP default window size—Sets the TCP default window size for AI232. The window
size specifies how many bytes AI232 will send to another device or how many
bytes another device may send to the AI232 before receiving an
acknowledgement.
Note: A small default window size way slow transfers to and from AI232.
zTCP send ahead—Enables or disables AI232’s ability to send a TCP window without
requiring an acknowledgment. When enabled, acknowledgment is not required.
When disabled, acknowledgment is required.
