RE: RS485 and EPICS

Chris,
	I have a GreenSprings IP-Octal-232, 422, and 485 driver (actually for the 
SCC2698 UART) that I wrote last year. Only the RS-232 portion has really 
been tested so far and I will be working on and with this driver over the 
next few months here at Los Alamos.

	It as written as a standard vxWorks tyLib-based driver and thus can be 
controlled by the drvSerial generic serial device driver used at Los 
Alamos, Keck and other places. There are several modules that sit on top of 
drvSerial (like drvAscii) that support concepts such as ASCII 
commands/responses and the Allen-Bradley DF1 protocol.

	I have been using drvIpac for the IP carrier interface.

Aloha,
	Peregrine
