Title text: My friend Finn tried to mail one end of the cable to me and thread the mail system.
At the time this comic was written, most residential buildings in North America were wired for analog devices using the old landline telephone services, although thanks to the growth of internet telephone and wireless telephone technologies, including cordless and mobile phones, this in-house wiring was increasingly redundant. See also Use of mobile phones.
At the time, people who took their internet access seriously would have preferred that at least some of the phone wiring and phone jacks in their residences were Ethernet (Cat-5 or Cat-6) wiring and (RJ45) jacks for providing wired internet access throughout their home, or in this case, to their neighbour's home, so that they wouldn't have to resort to Wi-Fi, which was then slower and less reliable than a wired connection.
The title text suggests that it shows a fanciful way of converting analog phone lines to digital ethernet lines by simply faxing an ethernet cable, since a fax machine is a tool for converting analog content into digital.
Since the faxing of the ethernet cable is apparently successful, the comic is not really about the conversion, but is instead a subtle computer network joke about tunneling, whereby you can embed one kind of network access protocol within a very different protocol. Herein lies the humour: Cueball and Megan are apparently under the impression that they can achieve a faster connection by tunnelling a high-speed protocol (ethernet) through a slower (landline telephone service) one. Generally speaking, this is not true. The only exception is when embedding a compressed data stream within a non-compressed standard. The performance boosts, however, are typically modest for lossless compression, and not the orders of magnitude difference our novices apparently hope for.
The title text, which is a reference to foonetic user relsqui, was changed to correct their name to "Finn" after they came out as agender. (This comic was presumably inspired by this conversation they had over IRC.)
