Re: (ASCEND) more stuff!



I tried 'typing blind' to a mail server's port 25 and was unable to get a
response to any command, all commands including "quit" resulted in nothing
ever being echoed back, the only way I was able to get out was to type the
escape sequence.

Shouldn't it be relatively easy anyway for Ascend to modify the code to
echo back characters?  Maybe we should put in a feature request for that.

Although I rarely use an Ascend to telnet out to a specific port it is
sorely missed on the rare occasions it is needed to help debug things.
