InfoConnect for Airlines VBA Guide
WRQFastFileTransfer Property
Returns or specifies whether InfoConnect attempts to use the fast file transfer feature.
Syntax
Remarks
With this feature, you can move files between your PC and the host many times faster than with the standard file transfer protocol. This property is relevant only when your host connection is through a network that uses the LAT, Telnet, or NS/VT protocol.

Use WRQFastCompression to specify how compression is handled during fast file transfers.

When a fast file transfer is in effect, the following properties are ignored:

WRQCompression

WRQEndCharacter

WRQExtraCharacters

WRQFrameSize

WRQStartCharacter

WRQTransferLink

WRQWindowSize

If you use the StartTrace method when fast file transfer is in effect, you won't be able to capture the actual flow of data.

If you run VAXLINK2 with the L parameter, a host log file is not created.

If ASCII files with records larger than 32767 bytes fail, you may need to set this property to WRQFastFileTransferOption.Never. (An error message is displayed that states if this is necessary.) This property is relevant only for transfers that use the WRQ/Reflection protocol.

The default value is WRQFastFileTransferOption.Negotiate.
  • Always uses fast file transfer. The transfer fails if the fast file transfer feature cannot be used.
  • Never uses fast file transfer.
  • InfoConnect attempts to use the fast file transfer feature, but falls back to a standard transfer if a fast file transfer is not possible.
