Hi all: There is a service here, that offers its servives mainly to travel agencies and airline agencies, they offer something similar to the 'Oficial Airline Guide (tm)'. Its commercial name here is SERTEL. The access to this system is made thru the switched telephone network or thru leased lines, but BOTH methods are synchronus, according to CCITT v.22 bis in respecto to the modem characteristics. The communications protocol used for this system is called ALC (Airline Link Control), and the software used (i guess on the mainframe hosts) is made by a company called Continental Computer Services. Here are some recomended systems (PC's) for using with this system, (as said by the system's manage- mente people): IBM PS/2, Unisys PW2 systems, Televideo Teletravel system, Memorex Telex, Megadata system. What we need, is technical information/description concerning this protocol ALC, and information about similar systems offering travel and airline stuff to the public or to travel/airline agencies. Also infor mation about the special characteristics that the systems above mentioned may have (a synch port in the first place, i guess...) to use SERTEL. (I mean just technical information wanted.) Any help is appreciated, thanks in advance, please respond by email. If interest is shown,i will sumarize to the network. Ed. logex@altger.UUCP
