| Based on the original DZ11 simulator by Thord Nilson, as updated by | |
| Arthur Krewat. | |
| 10-Oct-12 MP Added extended attach support for serial, per line | |
| listener and outgoing connections | |
| 17-Jan-11 MP Added buffered line capabilities | |
| 20-Nov-08 RMS Added three new standardized SHOW routines | |
| 07-Oct-08 JDB Added serial port support to TMXR, TMLN | |
| 27-May-08 JDB Added lnorder to TMXR structure, | |
| added tmxr_set_lnorder and tmxr_set_lnorder | |
| 14-May-08 JDB Added dptr to TMXR structure | |
| 04-Jan-04 RMS Changed TMXR ldsc to be pointer to linedesc array | |
| Added tmxr_linemsg, logging (from Mark Pizzolato) | |
| 29-Dec-03 RMS Added output stall support, increased buffer size | |
| 22-Dec-02 RMS Added break support (from Mark Pizzolato) | |
| 20-Aug-02 RMS Added tmxr_open_master, tmxr_close_master, tmxr.port | |
| 30-Dec-01 RMS Renamed tmxr_fstatus, added tmxr_fstats | |
| 20-Oct-01 RMS Removed tmxr_getchar, formalized buffer guard, | |
| added tmxr_rqln, tmxr_tqln | |
