+The '''Tektronix 834''' is a portable "programmable data communications tester" (serial protocol analyzer) for RS-232 (V.24) circuits, introduced in 1980.
+The [[835]] and [[836]] are sister models with extra features, introduced in 1986.
+[[John Light]] was the software lead on the 834 and wrote some of the key parts of the software.
+Other software team members included [[Jeff McMeekin]], [[Randy Deitrich]] and [[Bill Randle]].
+On the hardware side was Pete J, and [[Lynn Saunders]].
+[[Wendell Damm]] was the enginering project manager.
 It can be used as a serial transmission monitor, modem or terminal simulator, or as a bit and block error rate tester (BERT).
 It supports ASCII, EBCDIC and hexadecimal displays on its 12-character alphanumeric display, for data formats with 5 to 9 bits/ character (including parity), asynchronous or synchronous (including HDLC), from 50 to 19200 bits/s.
 ROM packs were available to extend the 834's functions for specific protocols.
