According to http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WCH the chip itself does not differ from one in card with dev-id 3253. So technically one can solder connectors and use this card as 2serial + 1parallel. But he could also remove link between pins 62 and 63 and get the board indentified as 3252. So, I believe, it would be less confusing (for users) if we do not create serial devices for this adapter. -- Best regards, Alexander Gerasiov Contacts: e-mail: g...@cs.msu.su Homepage: http://gerasiov.net Skype: gerasiov PGP fingerprint: 04B5 9D90 DF7C C2AB CD49 BAEA CA87 E9E8 2AAC 33F1
