serial port CTS monitoring

[Gilles Duguay]

I would like to know how to read the status of the Clear To Send (CTS) line.
I need this in order to implement a write with timeout vi, required when
using the RTS/CTS handshaking protocol.

Thanks
Gilles

If you run LabView under Windows NT, you need "hwaccess" from the NI ftp-
server for direct port access.

CTS is line 4 (2^4) at (port base + 6), the MSR (modem status register).
Ralf Browns interrupt list (especially the "ports.lst") shows many
details.

Viele Gruesse!
