[GreenKeys] USB to serial adapter

[Duncan M. Brown]

Don,

Recent vintage USB to serial converters will not work with TTY.  They don't
go that slow anymore!!  There is only one known USB to serial converter
that will work with TTY: the Belkin F5U103 - But they are hard to find
anymore!!

I use a PCMIA card serial port on my laptop for TTY connection.  There are
various level shifter designs using opto couplers for the interface between
the serial port levels and the 60 ma loop.  

Do you want to just drive the TTY from your computer (RO), or do TX & RX?

73,

Duncan, K2OEQ
