Synchronous comms thru Sun tty ports?

[Steve M. Burinsky]

I need to read synchronous data into a Sun via a serial port.  I am having
trouble finding any info on how to do this.  I know that the mcp and mti
boards (used as alm's) can support this, but I've only seen it done in
conjunction with a Sunlink software product like Sunlink X.25.  Also, I've
taken a look at the zs driver, but it only appears to support async comms
(although I believe the hardware will support sync comms).  Can anyone
help me out on this one?
