Errors do occur but the LAN software is suppose to detect and resend bad packets. The review for this particular LAN said that speed must drop for greater distances, with the lowest speed 19.2K bps for lengths around 1000 feet. I looked up the review, it is LANLink, it said the UART can handle 38K bps with no problem, but can go to 115.2K bps with an occasional error. With error correcting protocol, an error now and then can be tolerated. The review was in the August, 1985 issue of Business Computer Systems. -- Tim Lange Engineering Business Offices 317-494-5338 Rm 120 Engineering Administration Bldg.
