If a direct connection is available, the connection ! 37: will be immediate. ! 38: Once the connection is made, the screen will generally behave as ! 39: would a 3277 terminal. ! 40: .P ! 41: As ASCII keyboards do not generally have the same special function ! 42: keys as are available on the 3277, some keyboard mapping is required. ! 43: The mapping is done through a combination of ! 44: .I termcap ! 45: special key descriptions and use of a simulated status line area. ! 46: Special keys as described in ! 47: .I termcap(5) ! 48: and below may be defined for the terminal, or they may default as shown below: ! 49: .P ! 50: .TS ! 51: center,box; ! 52: c|c|c|c|c|c ! 53: c|c|c|c|c|c ! 54: c|l|l|c|l|l. ! 55: TERMCAP TERMCAP ! 56: Name Description Default Name Description Default ! 57: _ ! 58: S0 EM3277 Special Cntl-[ (037) P1 PF1 Cntl-Q (021) ! 59: Function (ESC) ! 60: S1 Enter Cntl-N (016) P2 PF2 Cntl-W (027) ! 61: S2 Clear Cntl-O (017) P3 PF3 Cntl-E (005) ! 62: S3 Backtab Cntl-U (025) P4 PF4 Cntl-R (022) ! 63: S4 Erase EOF Cntl-Y (031) P5 PF5 Cntl-T (024) ! 64: S5 Erase Input Cntl-P (020) P6 PF6 Cntl-A (001) ! 65: S6 Insert Mode Cntl-^ (036) P7 PF7 Cntl-S (023) ! 66: S7 Delete Char.

The last two lines of the screen will be ! 95: replaced temporarily with a status line and command line. The status ! 96: line indicates keyboard and system status (SYSTEM AVAILABLE, INPUT ! 97: INHIBITED, ...).

Processing aborted. ! 154: .TP ! 155: em3277 <host>: unrecognized keyword, line <l> in <filename>. ! 156: While reading the host configuration file <filename>, ! 157: an unrecognized keyword was found on line <l>.

Processing aborted. ! 165: .TP ! 166: em3277 <host>: device <devname> reports modem failure. ! 167: The named device reported a transmit timeout error. The usual reason ! 168: for this is that the device did not get a transmit clock signal from ! 169: the modem. This could be due to improper modem option specification, ! 170: improper cable to the modem from the computer system, or to not having ! 171: jumpered the MODEM port for external timing. Transmission is ! 172: aborted. ! 173: .TP ! 174: em3277 <host>: file <filename> can't be created. ! 175: While attempting to create <filename> to hold received printer data, ! 176: an error was encountered. Check the modes on the directory and/or ! 177: file. Printer data will be discarded until another special function ! 178: command for the printer corrects the problem. ! 179: .TP ! 180: em3277 <host>: <program> not found or not executable. ! 181: While attempting to spawn <program> to receive printed data, an error ! 182: was encountered. Check the program name and permissions on the file. ! 183: Printer data will be discarded until another special function command ! 184: for the printer corrects the problem.
