Re: Sending Telnet IAC-Character for a Command to an ExternalConnection

I think your best bet would be to set the stream to binary and then send the byte 255.

If you want to use a character, you definitely don't want Character digitValue:. That's not at all the same thing as saying that you want a character whose code in some encoding is 255, and in fact the character you get that way is Unicode 16r136, not 16rFF. You'd probably want to use #value: or codePoint:. But even then, you have no guarantee that that encodes to the value 255 in the underlying byte stream. If you want a byte, use a byte, don't rely on the character.

Hi,

i try to programm a Telnet-Connection to an external Switch. That works fine
until i want to send
an Command at the CLI-prompt to the switch. I have to send
Character digitvalue 255 followed by the CLI command with ExternalConnection
writeStream.

Here programm terminates with an "Unhandled Exception: This character is not
supported by this class of String"

I tried all possible StreamEncoders for ExternalConnection withEncoding, but
that doesn't help.

Cheers
