V0.1.2 live now

Minor fix to send CR+LF line endings instead of just LF.
Seems that most servers will support both, but some only support CR+LF, which is the telnet standard. So far I haven't encountered any servers that support only LF.

May need to do a force refresh (without cache) in your browser to pick up latest version.
