The device minor numbers for this driver are encoded as follows:
d c c p p p p p - bits in the minor device number bits meaning ---- ------- ppppp physical serial line (i.e. port) to use: 0-3 on Cyclom-4Y 0-7 on Cyclom-8Y 0-15 on Cyclom-16Y 0-31 on Cyclom-32Y cc card unit number; note this limits the driver to four cards per system d set to use as a dial-out line
cy
driver makes use of the CD1400's automatic CTS
flow control. In addition, the CD1400's automatic input flow control can be
used. This requires the kernel configuration option
CY_HW_RTS and a special cable that exchanges the RTS and DTR
lines.
Additional debugging output can be enable with the kernel configuration option CY_DEBUG. Diagnostic counters may be enabled with the kernel configuration option CY_DEBUG1.
