user resource

Type	Default	Option: -user
string		x3270	c3270	wc3270	s3270	b3270

Specifies the response to a TELNET NEW-ENVIRON sub-negotiation request, when the host requests the USER system variable.

If the user resource is not set, the response will be the value of the USER environment variable, if defined, otherwise the value of the USERNAME environment variable, if defined. If the user resource is not set, and neither USER nor USERNAME is defined in the environment, the emulator will return the string UNKNOWN to the host.

To force the emulator to return an empty string in response to a USER system variable request, set the user resource to an empty string, or set the USER environment variable to an empty string. There is currently no way to force the emulator to tell the host that the USER system variable does not have a value.
