3. Z and I Emulator for Windows Telnet connection timeout with error 657

Problem
Keyword for Telnet timeout.
Resolution

Z and I Emulator for Windows uses non-blocking sockets when connecting to a remote system. By default, Z and I Emulator for Windows waits for 3 seconds to establish the socket connection. When accessing remote terminals over a dialup network, this default wait time might not be sufficient and could lead to a connection failure and return the error 657.

The default time can be changed by adding the following keyword to the Telnet3270 or Telnet5250 stanza of the workstation profile:
[Telnet3270]
InactiveTimeout=xx
The value xx is the time in seconds and can take any positive numerical values.
