I have had great luck with the Keyspan HS19 (hispeed 19) about 30 bucks most places. Tom In a message dated 4/27/2009 9:13:35 A.M.

I have a ByteRunner 8-port USB-to-serial adapter, but it changes the handshaking signals too slowly. The CW works fine, but there's too much delay in the R1/R2 switching. It's not usable for SO2R switching and I have to use the motherboard port for the keyer. I may be moving to a MAC and running Writelog under Windows under VMWare, and the MAC doesn't support regular serial ports. Has anyone found a single-port USB-to-serial adapter that will work properly with the W5XD+ keyer? 73, Dick WC1M _______________________________________________ WriteLog mailing list WriteLog at contesting.com http://lists.contesting.com/mailman/listinfo/writelog WriteLog on the web: http://www.writelog.com/ **************A Good Credit Score is 700 or Above.
