PCCOM

PC Communication (PCCOM) is a Terminate-and-Stay-Resident (TSR) program for serial communication between two PCs. When linked together through serial ports, one PC serve as a Master while the other as Slave. The Master PC has control and can copy files to/from the other PC, perform file viewing, deletion, make/remove directory. The program has similar look to Norton Commander. PCCOM designed to work under MS-DOS but it can also be executed under Windows 10 and 11 through DOSBox. However, the connection feature between two PCs is only tested under MS-DOS environment.
