DROM(10.1) DROM(10.1) NAME drom, urom - read and write proms or pals through DATA I/O promwriters SYNOPSIS drom [ option ] ... urom [ option ] ... DESCRIPTION Drom serves as an interface to the RS-232 interface of the DATA I/O model 19 or 29 promwriter. Urom serves as an interface to the DATA I/O unisite programmer. Options are used to specify the prom type, and whether the prom is to be read or written. The f, J, and C options are only supported by urom. -w Specifies that the prom is to be written; default is read. -sn Specifies a starting address (default 0) in the prom in decimal. -tstring string Specifies the device type of the prom, a compiled in table is used to get the device code. -cn Specifies the code from the DATA I/O manual. Some plug in Paks, e.g. UniPak and LogicPak, require a code in which case either -t or -c must be specified, others require no code in which case neither should be used. Failure to follow these rules results in -n Causes the the program to echo the code that it is sending to the DATAI/O, and causes the DATAI/O the echo the size and ini- tial state specified by the code. No reading or writing is done. -b Causes a blank check to be run, the illegal bit test is run un- less it is an electrically alterable rom. No blank check is done if the rom is being read. -X -x Specifies hexadecimal data with upper case or lower case respec- tively. -C Specifies charactor data, for logic devices with JEDEC format. -D -d Specifies decimal data, octal is default. -fn Use format n. 50, the default, is for hex, octal, or decimal format files. 91 is for JEDEC files. -J JEDEC format (same as -f91 -C option) -i Causes the data to be (ones) complemented on input and output. -v Normally drom does it work silently, this is the verbose flag. To read an Intel 2716 prom using the UniPak one could say drom -t2716 or to write a National PAL16L8 using the LogicPak one could say drom -w -t NS16L8 < filename or to write it using the Pal Programming Pack drom -w -i NS16L8 < filename The input for logic devices on the UNISITE must be in JEDEC format. In this case use drom -w -t NS16L8 -f 91 -C < filename or drom -w -t NS16L8 -J < filename When a prom is read, the addressed locations are copied, one per line, onto the standard output. When a prom is written, the standard input is assumed to be of the same form, and is copied onto the prom. Vari- ous promwriter errors, such as the prom having a pattern that conflicts with the data (illegal bit test) when being written, are reflected back to the user. Transmissions over the RS-232 line are checksummed, and when writing the prom is verified. The speed of the prom writer should be set to 9600, position 14. The Model 29 promwriter must be initialized by pushing its buttons, SELECT F1 START START. FILES SEE ALSO xpal(1), pal(1) UCDS DROM(10.1)
