Port redirection policy settings 编辑

The Port Redirection section contains policy settings for client LPT and COM port mapping.

For Virtual Delivery Agent versions earlier than 7.0, use the following policy settings to configure port redirection. For the VDA versions 7.0 through 7.8, configure these settings using the registry; see Configure COM Port and LPT Port Redirection settings using the registry. For the VDA version 7.9, use the following policy settings.

Auto connect client COM ports

This setting enables or disables automatic connection of COM ports on user devices when users log on to a site.

By default, client COM ports are not automatically connected.

Auto connect client LPT ports

This setting enables or disables automatic connection of LPT ports on user devices when users log on to a site.

By default, client LPT ports are not connected automatically.

Client COM port redirection

This setting allows or prevents access to COM ports on the user device.

By default, COM port redirection is prohibited.

The following policy settings are related:

• COM port redirection bandwidth limit
• COM port redirection bandwidth limit percent

Client LPT port redirection

This setting allows or prevents access to LPT ports on the user device.

By default, LPT port redirection is prohibited.

LPT ports are used only by legacy applications that send print jobs to the LPT ports. These ports are not used by legacy applications that send print jobs to the print objects on the user device. Most applications today can send print jobs to printer objects. This policy setting is necessary only for servers that host legacy applications that print to LPT ports.

Note, although Client COM port redirection is bi-directional, LPT port redirection is output only and limited to \\client\LPT1 and \\client\LPT2 within an ICA session.

The following policy settings are related:

• LPT port redirection bandwidth limit
• LPT port redirection bandwidth limit percent
