Hi,
I have problem with my pabx that linked to hotel interface. There are no handshaking between the system. Anyone can email me the pms simulator so that i can determine which system is not working. Have done cable check, com port loop test but all look fine. I suspected the interface its self faulty. Need to confirm before contacting the vendor.Please help.

Thanks...
