well thats the problem.. it appears that the device cant just take a string whenever.. u have to initiate sessions, calculate checksums etc etc... the device is a videotek rs-12a. I thought u had to use the serial control device in catalyst to do this btw???
thats complex! for a switcher.
i have never seen or used these switchers-
i have done a control panel for kramer, extron, and some others- they are much easier-
----
if it uses a transaction protocol - i have to write software - and i need the device-
it looks like their may be a dumbed down version of the protocol that will work on this device... I hope so! I'll keep u posted just in case it comes in handy for someone in the future.
