20 | .SH NAME |
| 21 | mset \- retrieve ASCII to IBM 3270 keyboard map | |
| 22 | .SH SYNOPSIS | |
| 23 | .B mset | |
| 24 | .SH DESCRIPTION | |
| 25 | .I Mset | |
| 26 | retrieves mapping information | |
| 27 | for the ASCII keyboard to IBM 3270 terminal | |
| 28 | special functions. | |
| 29 | Normally, these mappings are found | |
| 30 | in | |
| 31 | .I /etc/map3270 | |
| 32 | (see | |
| 33 | .IR map3270 (5)). | |
| 34 | This information is used by the | |
| 35 | .I tn3270 | |
| 36 | command (see | |
| 37 | .IR tn3270 (1)). | |
| 38 | .PP | |
| 39 | .I Mset | |
| 40 | can be used store the mapping information in the process environment | |
| 41 | in order to avoid scanning | |
| 42 | .I /etc/map3270 | |
| 43 | each time | |
| 44 | .I tn3270 | |
| 45 | is invoked. | |
| 46 | To do this, place the following command in your | |
| 47 | .I .login | |
| 48 | file: | |
| 49 | .ti 5n | |
| 50 | .sp | |
| 51 | set noglob; setenv \s-1MAP3270\s0 "\(gamset\(ga"; unset noglob | |
| 52 | .PP | |
| 53 | .I Mset | |
| 54 | first determines the user's terminal type from the environment variable | |
| 55 | .BR TERM . | |
| 56 | Normally | |
| 57 | .I mset | |
| 58 | then uses the file | |
| 59 | .I /etc/map3270 | |
| 60 | to find the keyboard mapping for that terminal. | |
| 61 | However, if the environment variable | |
| 62 | .B MAP3270 | |
| 63 | exists and contains the entry for the specified terminal, then that | |
| 64 | definition is used. | |
| 65 | If the value of | |
| 66 | .B MAP3270 | |
| 67 | begins with a slash (`/') then it is assumed to be the full pathname | |
| 68 | of an alternate mapping file and that file is searched first. | |
| 69 | In any case, if the mapping for the terminal is not found in | |
| 70 | the environment, nor in an alternate map file, nor in the standard map file, | |
| 71 | then the same search is performed for an entry for a terminal type of | |
| 72 | .B unknown. | |
| 73 | If that search also fails, | |
| 74 | then a default mapping | |
| 75 | is used. | |
| 76 | .SH FILES | |
| 77 | /etc/map3270 keyboard mapping for known terminals | |
| 78 | .SH SEE ALSO | |
| 79 | tn3270(1), map3270(5) | |
| 80 | .SH BUGS | |
| 81 | If the entry for the specific terminal | |
| 82 | exceeds 1024 bytes, \fIcsh\fR(1) will fail | |
| 83 | to set the environment variable. | |
| 84 | .I Mset | |
| 85 | should probably | |
| 86 | detect this case and | |
| 87 | output the path to the | |
| 88 | .I map3270 | |
| 89 | file | |
| 90 | instead of the terminal entry. |
