Review Date: May 03, 2007


Strengths: Allows for multiple serial data to be sent at one time.

Weaknesses: I receive communication errors at times. It would be nice if it split the IRQ's instead of assigning it one.

Summary: This has been an excellant tool for my job as a field technician. It allows me to put new software into 4 radios at one time with a computer that does not have serial capability.
